Water Bottle Rocket

I will show you how to make a water bottle rocket that I made with poster board and bottles

1. duct tape
2. something to cut with
3. two 2litre bottles
4. paper
5. poster board
6. cardboard

gather the materials

lay the poster on a flat surface and set up the 2 bottles, when rolling the paper make sure to leave a good amount of the engine sticking out of the frame as shown in image one. Attach your fuselage to the board using duct tape, when its all rolled up make sure the rocket is a little loose so the engine can slip on when its full of air

you can cut the fins to whatever shape you want

I cut a folder in half and cut the tabs so i get a normal looking paper. When making the cone roll it to make a pointy side and an open side

What I did was put the cone on the top first and made sure the pointy end was straight. After attaching the cone to the top and making the nose point towards the sky, I attached the 3 fins then I was finished. The end.
