I made a rocket last night in about 30 mins even while documenting it. They are really simple to make.
Materials List:
Heavy duty Paper 2-3 peices

Tape

Pen

Scissors

Large Circular object (i.e. Pot Lid, coffee can lid, etc.)

PVC Launch tube

These images were taken from SpaceTec

Compressed Air Rocketry is well....just that rocketry using compressed air. I got this idea from my friend Blakestradamus. He has build these before and is quite the wizard. He was going to build one for some cub scouts that were coming over to his house to investigate engineering careers. I told him that I wanted to build one and that we could be two for twice the cost! What a deal!

I'm going to try and detail everything that I did to assemble the Compressed Air Rocket Launch Pad.

All of the materials can be picked up at your local hardware store. They should have all of these parts, but if not you can alter the design to the parts that are at your disposal.

2″ PVC Tubing - about 5 feet. This will be cut into 3 different pieces.

2″ PVC End Cap - 1

2″ 90° Elbow - 2

2″ coupler - 1

2″ to 1″ Reducer - 1

3/4″ slip / 1″ threaded joint - 2

1″ Sprinkler Valve - 1

1″ 90° Elbow / 1/2″ threaded - 1

1/2″ thread/slip joint - 1

Compressor air hose connector - 1

We already decided on a fin so there is nothing we relly need to talk about them. Except I like the other fin better, but what ever. Every other picture on this padlet has those fins.

I think we should use the top right fin because it is like the one we disscussed and we all liked these fins. They are likethe fins in Kolbrun wrote over there. ------>

# data[].attributes.body
I think we should use these shapes because they are meant to add speed to the rocket since their slopes are steep and they're narrow to limit air resistance. The rocket should be fast because it needs to push up against gravity so it can gain elevation. The fins should be made out of styrofoam because it's lightweight and easily cut. We want the fins to be light so there would be less gravity pulling the rocket down. With styrofoam, any fin shape can be created and will still be light.

# data[].attributes.headline
Kolbrun These are the fins we discussed 

# data[].attributes.subject
Kolbrun These are the fins we discussed 

# data[].attributes.body
I think we should use the fins above but longer down like the picture Kolbrun posted because if we use a fin that goes out to much, when it goes up into the air there will be less force because the air is pushing on the fin. We also want out fins to be a good weight because if it's to little then the rocket will be out of control and if it's too heavy then it might not go as high.

# data[].attributes.body
I think we should put our fins at the bottom so they touch the floor, unlike this one.

This experiment demonstrates how a build up in pressure can launch a rocket.

As we pump air through the water the pressure inside the bottle builds up until the force of the air pushing on the water is enough to push the cork out of the end of the bottle. The water rushes out of the bottle in one direction whilst the bottle pushes back in the other. This results in the bottle shooting upwards.

How to make a Bottle rocket

What you need

cardboard made into a cone and 4 fins

a pump with a needle adaptor

Instructions

Push the needle adaptor of the pump through the cork, it needs to go all the way through so you might have to trim the cork a little bit.

Decorate the bottle with the cone and fins.

Fill the bottle one quarter full of water and push the cork in tightly.

Take the bottle outside and connect the pump to the needle adaptor. Ours wouldn't stand up on the fins so we rested it on a table, but if you make some strong fins it should stand up by itself.

Pump air into the bottle, making sure all spectators stand back, the bottle will lift off with force after a few seconds.

Warning!

Please make sure an adult is around as the rocket takes off very suddenly and forcefully as you can see in this video clip. Do not approach the rocket once you have started pumping even if it looks like nothing is happening.

The Science bit

Space rockets work in a similar way to the bottle, but instead of squirting water they burn fuel to make a powerful jet of hot gas. The force of the gas downwards pushes the rocket upwards.

Isaac Newton worked out the three laws of motion which describe how all objects move. The third law says:

'for every action there is an equal and opposite reaction'

This is demonstrated by the bottle rocket.

Did you know we have a book available? Rocket Science is full of easy and exciting space themed activities perfect for kids of all ages. Click the image to find out more.

We recently tried a brilliant rocket kit from The Consortium which was VERY easy to use. We would definitely recommend it!

Extension Activities

Try one of these other easy air pressure experiments, including making a fake lung, a barometer and a coin popper!

We also love this collection of fun and easy garden games.

Did you know we have an Early Years book available to buy too?

I think if we put our seltzer bottle upsidown and capture air in the bottle. there will be more force to get it up into the air

# data[].attributes.body
For our rocket we need to reduce the drag. How you do this is by making the path up into the sky as smooth as possible

# data[].attributes.body
We need to keep our rockets weight to a minimum so it can go higher. We can't have the rocket way to little either though because then it will be very difficult to even take off.

# data[].attributes.body
That made me think that we should get a scale and weigh our rocket when done so we can get it to go up higher because we would know how much it weighs.

# data[].attributes.body
First order of business:

Our nose cone should be like the one Christian was talking about.

i.e. The elliptical cone⬆

Second order of business:

We have to use the 1st law of motion!!! But, since there is gravity, we must counteract the force. Like Mili said, not to light but not to heavy.

Final order of business:

No frivolous decorating

# data[].attributes.body
This nose cone is round but not to flat so I think this nose cone would be the best one for our rocket

# data[].attributes.body
i think our rocket should

This picture shows the bottle capon the bottom. For force I think we should capture air into the bottle and then when it is ready to launch we could take the bottle cap off and the air force will make it go really high.

I think we should also use acssesories to make our rocket pop.

# data[].attributes.body
I think we should have something like this but a lot more colorful but it should have a nose cone and fins.

# data[].attributes.body
I think our fins should be different colors as well as the tape because I want our rocket to pop. This picture doesn't mean i want the fins different sizes.

# data[].attributes.body
I think we should use a balloon as our fuel because if we stick the balloon in the bottle it could shoot up into the air.

# data[].attributes.body
We should have fins at the bottom of our rocket so it goes higher and faster.

# data[].attributes.body
This is the size of the nose cone that will cover the bottle. And we can use the duck tape to make it look colorful.

# data[].attributes.body
I think we should use colorful duck tape to make our rockets pop.

# data[].attributes.body
I was inspired to use this picture because it shows different kinds of rocket fins and if we only try one and it doesn't work we won't have any other ideas.

# data[].attributes.body
This is the bottle that were using so find a nose cone that looks like it can fit on the top of the bottle.

# data[].attributes.body
I think we should do this with our rocket so it will help the nose cone from falling off the bottle and then we won't be waisting duck tape

# data[].attributes.body
I was inspired by this because it has the right sized bottle and I think at the end most peoples like this.

# data[].attributes.body
I chose to use this picture and was inspired by it because it shows the length of the rocket, the width and the height with letters which tells me that this will help us figure out how our rocket should work and be like

# data[].attributes.body
I think we should use the top left fin because I have seen that one on a lot of rockets and it is the most comman for me.

# data[].attributes.body
I think we should use this one because because it's good and ready to make

# data[].attributes.body
I was inspired to use this picture because  it shows the different sizes of nose cones. Some are sharp and some are flat so it can give us ideas on researching about what is a better nose cone: sharp or flat. When we find out which nose cone is better we will have a better chance of having a good rocket.
