Here we will detail step by step how to build and lauch your own rocket.
Please make sure your are following the step good and use the right tools.
Step 0
To make a rocket you will need at least 3 or 4 soda bottles try to take the same, scotch,scissors and stapler or glue.
Then you need a cork plug, a valve to inflate your ballon and to finish a bicycle pump.
Step 1
Take one of the bottles and cut the upper part and the bottom part.
Keep the upper and the middle part and throw the bottom one.

Step 2
Take another bottle and cut the ailerons out of it, you can also take a cardboard and cut the form you want, here we will take the bottle and a specific form to improve stability.
Repeat this 3 or 4 times and use the third bottle if you need. But you must have a fourth one to make the rocket.
Step 3
Now you must assemble the ailerons.
Take the middle sliced part and the ailerons you cut.
Bend the form on the dotted line and fix with glue.
Then you can staple them to the middle part, they have to be equitably distributed.

Step 4
Now you have to assemble the upper sliced part with the intact bottle.
Take the bottle and put the sliced part to it's bottom.

Step 5
Then you have to take the product you made at the step 3 and you add the one of the step 4.
To do so you have to put the ailerons part on the upper part of the intact bottle.

Step 6
Now take the cork and put the needle to inflate bollons in it, try to focus the center of the cork.

Step 7
Now fill up to the middle the bottle of your rocket and close it with the cork.

Step 7'
If you are making the pressured air one, pass to the next step.
Step 7''
If you are making the chemical one, watch out it can be dangerous.
To do so you will need some baking soda and white vinegar.
Then fill the bottle to the quarter with the vinegar, now put some baking soda on a tissue and make a ball with it.
Try to block it with the cork in the bottle and try to don't have any contact between vinegar and baking soda.
To start the reaction just turn over the bottle. It will take little time so be patient and put the bottle 2m away.

Step 8
Now place your rocket on a ramp or on place where it can stands up,
Then plug the bicycle pump and start to pump to add some pressure, when the pressure will be enough the cork will be eject and the rocket will start to fly.
