They all swing and 2 and 3 are different sizes

# data[].attributes.body
I noticed that all of them started with some outside force.

# data[].attributes.body
I believe the videos are called so because the experiments are based on each scientists discovery.

# data[].attributes.body
I observed that if you don't push the ball it won't hit the person's face.

# data[].attributes.body
I observed that when the marble moved from the one end then one marble moves on the other.

# data[].attributes.body
I observed it moved after it was winded up and it fell off right after 2 seconds.

# data[].attributes.body
I observed that it spinned 1 min 53 sec.
It spinned longer than top 1.

# data[].attributes.body
I observed that it spinned 43 sec.

# data[].attributes.body
All the pendulums swung.
Pendulum 1 was smaller.
Pendulum 2 and 3 was bigger.

# data[].attributes.body
I observed that pendulum 3 stopped  much slower that pendulum 2.

# data[].attributes.body
I observed that it stopped swinging much faster than pendulum 1.

# data[].attributes.body
I noticed that the pendulum started swinging strongly and then it slowed down and stopped.

# data[].attributes.body
I observed that the can rolled when it was pushed and rolled back at some point.
I wonder why the can rolled back if it was on the even surface?

# data[].attributes.body
I observed when the flashlight reflected on the bulb the square thing started spinning around and when the flashlight was removed it started slowing down and gradually stopped.
The common reason why the device started and stopped working was the light flashed in it and stopped.

# data[].attributes.body
I wonder how the car stayed upside down and was moving.
I noticed it was a domino effect.
how long did it take to finish this project?

# data[].attributes.body
I wonder how does it go the same speed as like the other videos.

# data[].attributes.body
I notice that the ball way going for a long time until it started to slow down.

# data[].attributes.body
I saw that the can was moving from front to back when it was touched once.

# data[].attributes.body
I observed that when the flashlight when facing the globe the light spins and when it turns off it still keeps spinning.

# data[].attributes.body
I wonder how everything turn out to be good and that they use the right materials.

# data[].attributes.body
at the beginning of it swinging it sped up then slowed down

# data[].attributes.body
I noticed it was going the same speed for a long period of time

# data[].attributes.body
I wonder what materials they used

# data[].attributes.body
You need something to start another thing.

# data[].attributes.body
I noticed that the ball didn't hit the man, and I wonder how that was possible.

# data[].attributes.body
The video won't work for me.

# data[].attributes.body
I noticed that the toy operates after a couple of twists.

# data[].attributes.body
I wonder if that is a magnet, and if it is, then how is it possible?

# data[].attributes.body
I wonder why the spinner spins in the direction they are going to.

# data[].attributes.body
You need to give it a little push or spin like when teaching a kid on how to ride a bike like you give them a push same thing with these experiments.

# data[].attributes.body
The thing the makes things move is the force and the momentum items have and the shape because those things really determine if an item can move.

# data[].attributes.body
I think it is called this because they are taking 2 scientists and experiments and seeing which is better.

# data[].attributes.body
It might be called that because its telling peoples newtons law in a fun way.

# data[].attributes.body
I noticed that the ball wouldn't hit him, so the ball lost more and more swinging power.

# data[].attributes.body
would not load for me

# data[].attributes.body
it starts with someone moving it and makes the reaction .

# data[].attributes.body
What makes things move is a force.

# data[].attributes.body
I noticed that it kept on going and it did not stop.

# data[].attributes.body
An object doe snot gain energy when its moving.

# data[].attributes.body
I noticed that every time the ball hit the others it would make force for the last ball and launch it away.

# data[].attributes.body
I noticed when he twisted it it started moving fast.

# data[].attributes.body
maybe it called that because he is trying to show people another way of newtons law .

# data[].attributes.body
I noticed that the ball lost energy while swaying forward and then going back so it slowed down and it didn't hit the persons face.

# data[].attributes.body
I observed that most of the items were upside down.
I don't know why its called this.

# data[].attributes.body
Energy starts the reaction and when it stops the device stops moving.

# data[].attributes.body
i observed that when you are filming a video you need to edit .my perdition that its hard to do a chain upside down.

# data[].attributes.body
I think its called that because it's comparing what the 2 scientists discovered and which one wins in the video.

# data[].attributes.body
I noticed that every time it went to the middle bump it would speed up and it would get pushed to that bump because of the shape of the cup and it would just keep on going until somebody stops it.

# data[].attributes.body
I observed that the that he was holding a bowling ball. I noticed that the fake face in the beginning looked like the second man. I wonder why the second man would risk his face.

# data[].attributes.body
I noticed that pendulum 3 never slowed down unlike pendulum 1 and 2.

# data[].attributes.body
I observed that when that force hit the first ball that force traveled threw the other balls ending up in the last ball making it sway back and then hitting the balls again.

# data[].attributes.body
The video would not load fo me

# data[].attributes.body
Pendulum 2 and 3 had the same design and 3 didn't stop.

# data[].attributes.body
I observed that it was kinda quick when it was put down but 2 seconds later it slowed down and then fall off the table.

# data[].attributes.body
I noticed that there was a circle in the middle looked like black tape maybe that helped it move.

# data[].attributes.body
I wonder why the spinner was faster in the middle, but when on the sides it was slower.

# data[].attributes.body
There getting energy and its making something happen

# data[].attributes.body
i wonder why the bowling ball didn't hit his face ?

# data[].attributes.body
I notice how at the end of the video the spinner keeps spinning and they cut it off.

# data[].attributes.body
Top number 1 fell down and was spinning in circles while top number 2 didn't make any shape it just went in different directions and it also didn't lose its momentum.

# data[].attributes.body
he was trying to prove his point for the law of gravtiy

# data[].attributes.body
I noticed that this video is very similar to the pendulum 2 video.

# data[].attributes.body
how is it still spining without no flashlight

# data[].attributes.body
i noticed that when one or two marbles hit with the other marble .

# data[].attributes.headline
what make things work is you have to give it a bit of a start so it starts 

# data[].attributes.subject
what make things work is you have to give it a bit of a start so it starts 

# data[].attributes.body
that don't use force to the ball but you have to do it gently

# data[].attributes.body
I observed that everything was made of metal. I noticed that there were multiple balls and strings. I wonder how those balls move like that.

# data[].attributes.body
I noticed that it does not come back with the same amount of energy but less. Why does it not come back with the same energy?

# data[].attributes.headline
maybe it called that becuase his is trying to show people another way of newtons law 

# data[].attributes.subject

# data[].attributes.body
I noticed it took one slight push to have it swinging for two minutes.

# data[].attributes.body
The pendulums were the same in one way they all swung, but 2 stopped while the 3rd one didn't.

# data[].attributes.body
I wonder why does it take 2 minutes for a pendulum to slow down?

# data[].attributes.body
I noticed that it was spining super fast and went in circles but then it started to shake a little bit and thats when it stopped and fell down.

# data[].attributes.body
I observed that the pendulum was pushed high enough for it to constantly swing and not stop.

# data[].attributes.body
it moves back and forth because its pendulum but doesnt hit him

# data[].attributes.body
i observed that the windup critter has to be twist 3 times for it to move .

# data[].attributes.headline
i observed that since it was at a certain length it will not hit him  

# data[].attributes.subject
i observed that since it was at a certain length it will not hit him  

# data[].attributes.body
I observed that the machine looked like it had a wheel in the middle. I noticed that the wheels looked like boat propellers. I wonder how long it took to build that.

# data[].attributes.body
however many you hit with it it will move the same amount the other side, and it is a repetive thing .

# data[].attributes.body
the thing went fast then it just stumbled

# data[].attributes.body
that the ball made a foce and it made a chain reaction

# data[].attributes.body
i noticed that the spinning top 1 stops and the spinning top 2 doesn't stop .

# data[].attributes.body
I noticed that when one marble hits a side the other side does as well. Why does it do this?

# data[].attributes.body
The first pendulum has a different building design from 2 and 3 and it did slow down and stop at the end. 2 and 3 had the same building design but 2 stopped at the end but 3 didn't stop at all it kept its momentum.

# data[].attributes.headline
i observed that when it was hitting the ball force was created making the other ball move 

# data[].attributes.subject

# data[].attributes.body
I notice the ball was slowing down but never stopped.

# data[].attributes.body
I Noticed that when the spinner started spinning when it moved around the plate it got slower, bu when it got to the middle it was faster.

# data[].attributes.headline
all of them are made by the same way and the difference is that they all go in there same pace

# data[].attributes.subject

I observed that pendulum 2 was slower and and swung less then pendulum.

i noticed that when winding it up it starts moving and if you winded it up more it shold walk for more time 

# data[].attributes.subject

# data[].attributes.body
I noticed that the pendulum is swinging by itself, but I am wondering how it does that.

# data[].attributes.body
I observed that this is the same pendulum from number 2 but it didn't stop or slow down so something is making it go fast. Whats the difference from pendulum number and and pendulum 3?

# data[].attributes.body
I observed that the surface was a little bit dented. I noticed that the top was the same metal top from the last video. I wonder how the top stayed on that small surface.

# data[].attributes.body
i observed that it stop in the middle and it started in the middle.

# data[].attributes.body
that the guy pushed it far enough to not stop

# data[].attributes.body
its like a car that you load up by driving it backwards and it just zooms when you let go because you spring it up.

# data[].attributes.body
that when you wind it up it was going and walking around and it was getting faster and then slow

# data[].attributes.body
I noticed that when you wind it up it moves by itself. How does winding it up make it move?

# data[].attributes.headline
i think that it might keep spinning becuase there could be a magnet 

# data[].attributes.subject
