I noticed that the whole machine consisted of about 17 small mechanics to make up the whole machine. I also observed that throughout the machine  at almost the very end there was a bit of a turn upside down in the camera before showing the last mechanics. One question I have is how many times did they have to fix the machine for it to fully operate like it did in the video?

# data[].attributes.body
First I noticed that this machine used kinetic and potential energy. I also noticed that this is a easy machine and doesn't require anything you wouldn't have at home. My question is that is this machine always effective?

# data[].attributes.body
I noticed right away that something was wrong because they were dropping upwards and I realised it was upside down. I also noticed that every single little machine had a way to connect and start another. A question I have is, when the ball hit the wall with another ball on the other side, How did it start?

# data[].attributes.body
I observed how things are going upward when they'd usually go down, or to a different side then normal. I also noticed how quickly everything moved about how some things popped up into the air when meeting the other pieces in the Rube Goldberg Machine. My question is, How could the pieces of the experiment move upwards? As well as, Were there any magnets involved in this experiment?

Flashlight observations, Common reason why the devices start and stop

# data[].attributes.subject
Flashlight observations, Common reason why the devices start and stop

# data[].attributes.body
I had noticed that once the flashlight had been shown on the radiometer (I think that's what it's called) the metal squares inside had started moving faster and once the flashlight was gone it had slowed down a bit. I think that a common reason all devices start and stop is either because they don't have the energy to keep going and just stop. Most devices use an object or something to give it power to run and like the radiometer, the flashlight gave it energy to start and after a bit of time the metal squares had stopped going.

# data[].attributes.body
I noticed how the metal ball rolled up the first time, I was confused. I Observed that those little balls right after the metal ball was going up another bowl and then jumping out not even touching the table and landing inside! Question: Would Kinetic and/or Potential Energy have something to do with this?

# data[].attributes.body
I noticed that when the flashlight was added the device was moving faster and when the flashlight was taken away its moved slower. I think a common reason why all devices start and stop is because they run out of energy.

One observation, What is happening outside the can 

# data[].attributes.subject
One observation, What is happening outside the can 

# data[].attributes.body
I noticed that as soon as the can had been gently pushed it started swaying side to side until it slowly stopped. I believe that without opening the can, there might be a sort of liquid inside that is swaying from the inside and because of that, it makes the can move from side to side as well until the liquid stops and then the can stops as well.

# data[].attributes.body
I observed that when the can was given a slight push it started moving. My question is how did it keep on moving after the push?

# data[].attributes.body
I observed that everything had to move together for it to work.
I wonder how everything else flipped when the camera flipped.
I noticed that the apple hit newton's head so he found gravity but newton did not win though.

One question is that how does everything move so perfectly?

# data[].attributes.body
When the flashlight was put near the bulb I saw that the paper started moving faster and faster and when he took it away it went slower until it stopped completely. I think that what I just saw was a transfer of kinetic energy.

The paper inside the bulb is similar is shape and size, but the color is different as for 2 of the paper squares they were white, while the other 2 paper squares were black.

# data[].attributes.body
I observed that by pushing the Pendulum high in the air, it had gone fast swaying up and down faster than it did at the end because by swaying it at first, it had gone high in the air but then throughout the video it slowly stopped, an example just like the Pendulum is a swing once you go high in the air and then just stop swinging the gravity will stop you from going high without your help. So if you stop then your swing will stop swinging fast until the swing stops all the way.

# data[].attributes.body
one thing I observed was that there was a lot of movement with the machine and the camera. another thing i observed was that they used a lot of magnets. one question that I have i, how many times did they have to do it to get it perfect?

# data[].attributes.body
I observe that the machine went really fast. I observe that this machine was made out of home products. One question I have is: How long did it take to make this machince.

# data[].attributes.body
I noticed that it used 17 thing to help the ball move. I also noticed that most of the things in the video are made out of metal. My one question is that how did the ball stick to that bowl.

# data[].attributes.body
I observed that the pendulum had started of really fast but it gradually slows down before stopping

# data[].attributes.body
I noticed that the pendulum moves quickly at first but by the end it moves in place.

# data[].attributes.body
I noticed that before they had pushed the pendulum high in the air, it had already started to move based on the shakiness of the table. So even if they didn't push the pendulum it could have started moving if the table moved or shaken as well. Also the pendulum had gone fast at the begging and had moved for about more than a minute

# data[].attributes.body
When the guy pushed the paper cup with his hand it started rolling by itself. I know what I just saw was kinetic energy, it transferred from the hand to the cup making it go and roll away and back by itself.

# data[].attributes.body
I observed that different objects trigger another different object. I wonder what's it for and if the little thing at the end was for a game? Lastly I noticed how at the end of the video this little score popped up on the screen.

# data[].attributes.body
I noticed that with the flash light it went faster but without it it went slower. I think the common reason why it starts or stops is the flash light.

# data[].attributes.body
I observed a little ball that started all of the experiments, I also noticed that there were two different places where all of this was taking place, in the floor and in the ceiling. I wonder how they kept the table and experiment from falling on the floor if it was in the ceiling?

# data[].attributes.body
One observation I saw was how everything started coming alive with one little fan. Its my question too, how did it do all that? you would need much more kinetic energy to pull of something like that.

# data[].attributes.body
I noticed that when the light was applied it started it move but the when the  light was taken away it stopped moving.
I think that the radiometer does not give off light but the flashlight does. The similar thing is that the radiometer is like a light bulb.
Every device starts and stops because when the device turn on it is for our want so that's why it starts and it stops because it need rest or it will explode.

# data[].attributes.body
I had noticed that the third and final pendulum had moved for more than a minute as well as the second one and I noticed that this one had gone faster a bit more than the second one because they had pushed the pendulum farther than they did with the second

# data[].attributes.body
I observe the guy pushing the cup with his hand and made it start rollling. I think it starts rolling because of the force of the mans hand and how dense it is.

# data[].attributes.body
I noticed how a hand took the ball and swung it on a swing and it moved there on by itself, It then slowed down. This is because of kinetic energy, and later on in the video it went slower and then stopped because it didn't have enough kinetic energy to swing higher.

# data[].attributes.body
1. I observed that the back of the thingys spinning in the light bulb shapes container had a black side and a white side. I noticed that when the guy shined the light into the bulb the things inside it started spinning a lot.
5. I feel like a common reason devices stop and go is because they need SOME sort of energy to power up, and when the object no longer had that energy, it powers down. And I'm guessing that bulb uses some solar energy to power up because when the person shined light to the bulb it started spinning and when he took away the light it started powering down.

# data[].attributes.body
I noticed that all three pendulums were similar because they all had gone very fast at the beginning but then had gotten slower throughout the video. Some things that were different between them is that the second and third pendulum had shown that they could move without getting a little push and something else that was different is that the third had gone faster for more time and didn't get too slower. The third had still moved even when the video stopped!

# data[].attributes.body
I observed that the person pulled the  Pendulum and it started to move it lasted till 2 minutes and got slower and slower. Then It stopped.

# data[].attributes.body
An observation I made was how the objects were going upwards instead of down and another observation I made was that everything was moving slowly so a question I have for this is why was it moving so smoothly?

# data[].attributes.body
I observed that one action is needed for another. I noticed that there were many machines needed for this experiment. I wonder how all those machines were able to make such a cool reaction

# data[].attributes.body
The design of the pendulum was a more compact and small design. It had 2 balls instead on one, there was one on the top, a small one and a big one on the bottom, very big. Other then the priming mechanism being different, it pretty much did exactly what pendulum one did.

# data[].attributes.body
I had counted and seen that the spinning top had moved for about thirty seconds throughout the video. I also observed that since the plate was so big the spinning top had gotten to go in big circles near the beginning. Until the end when it had gotten slower and just went i tiny circles until it fully stopped.

# data[].attributes.body
An observation I made was that there was 2 places that the experiments were in the ceiling and in the floor. Another observation I made was that most things were magnetic. A question i have was how did the set everything up in the ceiling.

# data[].attributes.body
I observe that it went fast at first then slow at the end.

# data[].attributes.body
i noticed when the light was on it started to move.

# data[].attributes.body
This was basically the same design as pendulum 2 but it swung more and never stopped during the whole video. I don't know what they changed but it worked.

# data[].attributes.body
1.I noticed that a lot of random things were happening in this video. 2.Also I noticed that they were upside down. 1.How did they do it like that.

# data[].attributes.body
I noticed it started to move when he put the light on the bulb. The little plates started to go faster the longer he had the light on it.

# data[].attributes.body
Pendulum 1 had the biggest design out of all of them, but swung higher than pendulum 1 and 2 because it was just bigger, pendulum 1 and 2 had the most compact design, they both looked the same however pendulum 3 never stopped during the whole video. I don't know what they changed in pendulum 3 but it worked.

# data[].attributes.body
I noticed when the flashlight was on, the blades started spinning and weren't when they turned the flashlight off. A common reason why devices start and stop is because it gives us a chance to control the device.

# data[].attributes.body
I noticed that he pushed the cup and it came back to him. I think it came back because there's either something inside of it or the air around it is pushing it back and forth.

# data[].attributes.body
1. I observed that when the person pushed forced into his fingers into the rolling object the object moved forward and rolled back and forward until it stopped.
2. I one question I have is does the object have anything inside that makes it roll that way?
3. I can determine that there's an object inside the can?

# data[].attributes.body
1.When the flashlight was pulled closer to the light it was spinning faster. 2.But when it was pulled away it stopped spinning.

# data[].attributes.body
I observed that when the flashlight wasn't there the little piece of paper that were inside of the light-bulb weren't moving, but when they added the flashlight the papers inside the light-bulb started to move and while the longer the flashlight was there the more faster the papers would move.

# data[].attributes.body
I recorded how long the spinning top had gone and it had gone for about a minute and 17 seconds (I would have gone more but the video had stopped). I also noticed that the spinning top #2 had gone longer because I believe that based on the plate and the walls, the first spinning top didn't get to keep spinning because it had gotten stopped and blocked by the edges of the plate while the second spinning top didn't have any edges and even though it didn't have much space like the plate it still was able to spin longer because there was nothing blocking it like the plate edges.

# data[].attributes.body
1 thing i observed was that everytime they put the light of the flashlight on the light bulb  the things inside of the bulb were spinning faster.
1 similar item was the light bulb.
I think devices start and stop because some can get overheated and eventually explode.

# data[].attributes.body
I noticed that when the flashlight was lit towards the light bulb shape thing, the object inside started to circulate and when the flashlight turned off and was taken away it started slowing down.

# data[].attributes.body
I observed that the cup was still rolling even though it was not being oushed around.

# data[].attributes.body
from what I saw the top span for about the mid 40 and 50 seconds. I know how tops work and its because of balance and kinetic energy yet again.

# data[].attributes.headline
Observations, question, What is happening 

# data[].attributes.subject
Observations, question, What is happening 

# data[].attributes.body
I observed that the cup moved from left to right.
I wonder how it kept moving without anyone rolling it.
I noticed that the movement got slower and slower.

My question is what is moving the cup?

We can determine the object without opening the can by its sound.

# data[].attributes.body
I noticed that when he pushed it the ball went really fast and it slowed down after about 2 minutes of moving around.

# data[].attributes.body
I observes when the roll was pushed it came back. I wonder how it was able to do that. I think that there's some type of object in the can that's causing it to move forward and back.

# data[].attributes.body
I observed that when the guy pushed the cup it went rolling and then it rolled back. Why did the cup roll back?

# data[].attributes.body
The top was the same except the disc it was on. The top never stopped during the whole duration of the video so from what I am guessing it was the plate it was on the effected the time it spun.

# data[].attributes.body
I observed that when the person pushed the sphere, it started to move and then it stopped and went the other way and stopped again and started to move back and forth until it stopped. I wonder what caused that because normally when you push something in a table it would fall down to the floor?

# data[].attributes.body
The pendulum was moving very fast and it was swinging for a very long time even though it was only just a few minutes.

# data[].attributes.body
I noticed that when the pendulum was pushed it started off fast but it got slower and slower until is stopped.

# data[].attributes.body
This was like the last one but with a different design. It has a little ball and a big ball on the top.

# data[].attributes.body
1 thing i observed was that the can rolled all by it self.
1 question i have is if the can was being pulled by a magnet or was there something inside of it.
i think inside the can there is a magnet and it was being pulled by another magnet.

# data[].attributes.body
I observed that it took a while for the pendulum to go back to its normal state without rocking back and forth. I feel like the way the guy pushed it and how its tied made it so that the pendulum would rock back and forth for a while.

# data[].attributes.body
I was the same as the last one but this time the guy spon it more and it went for a lot longer.

# data[].attributes.body
I noticed that this pendulum was also like the last one because it started off quickly and swinged high and then it started slowing down and its swinging got lower so it took this pendulum about 2 minutes to stop swinging.

# data[].attributes.body
I observed that once it was pushed, the pendulum was still swinging for a while. I wonder how it was able to swing for that long. I noticed that it still got slower as the time went on but it still was swinging.

# data[].attributes.body
It felt like a very long time for it to stop even though it was almost 2 minutes.

# data[].attributes.body
I observed that the speed was the same for the beginning.
I wonder how it kept going so fast without anyone touching it again.
I noticed it got slower and slower when it was about to stop.

# data[].attributes.body
The things that are the same is that most of the use kinetic energy and most of them are made out of metal. The things that are different are there models and how long they go for.

# data[].attributes.body
It took longer than pendallum 1 and 2 to stop even though this was also used for pendallum 2.

# data[].attributes.body
There all different because they stopped different times even though they start at the same time.

# data[].attributes.body
It spon for about a minute and it kinda reminds me of a mini razor blade. It also uses kinetic energy to balance itself so it can spin for longer.

# data[].attributes.body
I observed that it started really fast and it slowly slowed down until it stopped.

# data[].attributes.body
I observed that the pendulum (1) when the person pulled it and then let it go is starting to move back and forth and wouldn't stop me until it was getting slower.

# data[].attributes.body
1. I observed that the pendulum has a ball and a little tiny ball on the top of it, which probably makes it swing the way it swings now. I feel like without the tiny ball on the top makes it swing more and without it it was have a less powerful swing.

# data[].attributes.body
It was the same as the last one but it has a smaller space to spin around. It also didn't spin as long compared to the last one.

# data[].attributes.body
I noticed that pendulum 2 had 2 balls instead of one and that it took about 2 minutes for it to stop.

# data[].attributes.body
I observed that the speed did not stay the same.
I wonder why it takes so long for it to stop.
I noticed that one side is much more bigger than the other side.

# data[].attributes.body
It spun for 1m & 53s. They are different because they stopped at different times.

# data[].attributes.body
I observed that the ball in the bottom is probably causing the pendulum to swing. I wonder if it was designed specifically to swing for a long period of time. I noticed that the push wasn't really with much power.

# data[].attributes.body
I noticed that this pendulum moved quicker and kept swing until the end of the video.

# data[].attributes.body
The 3 pendulums are similar by their swinging because it swung at the same pace until it stopped and the 1st 2 pendulums swung for about the same amount of time and 2 and 3 had the same design but what's different about them is 1 had a different design and 3 kept swinging to the end of the video and kept swinging when it was the end.

# data[].attributes.body
I observed that it took pendulum 3 about 3 minutes for it to stop.

# data[].attributes.body
I observed that the heavier cannot flip over the bar.
I wonder why one side is heavier.
I noticed that the smaller side goes much more farther than the bigger side.

# data[].attributes.body
I observed that this pendulum is kind of the same as the first pendulum, except that instead of having two strings tied to it, it has a piece of metal stuck to it and another ball but smaller. It does the same as the other pendulum it goes back and forth. It takes a lot of time for the pendulum to stop once it started to move.

# data[].attributes.body
1. I observed that it kept swinging through the whole video.
2. I wonder why it kept swinging throughout the whole video and how?
3. I noticed that the ball might be the exact same weight as the ball on the bottom, so therefore maybe that's why it could be swinging for a long time?

# data[].attributes.body
1. I noticed how when the balls were getting into the upside bowl without falling out.
2. I observed how the string unwinded itself like kinda like a snake.
Q : How many times did they had to do this?

# data[].attributes.body
Something all pendulums have in common is that the all have silver balls and that they move quickly and they slow down at the end.
Something that is different is the time they stop.

# data[].attributes.body
They are the same because it take almost the same time for all of them to stop. It is different because the pendulas look different.

# data[].attributes.body
The top spun for about 40 seconds and an observation I made was the top was able to move around the plate instead of staying in that one place where it was spun.

# data[].attributes.body
I noticed that the 3rd pendulum was still swinging higher when it finished than the 2nd one. I wonder if the higher the ball is, the longer it would swing.
