Picture of How To Make A Bottle Rocket
 It's simpler then it sounds to make a working bottle rocket and doesn't cost you much money. You only need a few materials. Getting the rocket assembled is easy..but getting the parachute to launch is a bit harder.

Step 1: Get Materials

Picture of Get Materials
Two 2 litter soda bottles.
A Garbage bag or plastic bag (for the parachute)
Duct tape
Cardboard or foam core
A Tennis ball 
Dental floss or string 

Step 2: Cut the bottles

Picture of Cut the bottles
Once you have all your materials get your bottles.
One bottle you're not going to anything to, which will be your bottom bottle that will connect to the launcher.

 The other bottle you're going to cut the top so you have the bottom of the bottle. 

Put the bottles together (DO NOT TAPE THEM) to make sure they're cut right before you move on.

(The picture is what the bottles should look like after you attach the wings and make the parachute.) 

Step 3: Make the wings

You'll need the bottom bottle, cardboard or foam core, a pair of scissors, duct tape, and if you want a pencil.

Get the cardboard or foam core and cut out a wing that will a good size for the bottle. 

Cut out 3-4 wings that are the same in size. If the size is off it will effect how high the rocket launches. You can make them whatever size you want and whatever shape you want. 

Once the wings are cut out, tape them onto the sides of the bottom bottle of your rocket so it looks somewhat to the picture. Make sure they're taped around the same height because the wings effect the direction and the height of the rocket.

how do u make the parachute stay to the bottle so the parachute can land on the ground safely?????

what does "Then once the string is tied to the bag you cut a hole in the tennis ball so the string can fit through and get to the other side of the tennis ball. Then make a hole in the piece of cardboard or foam so the string can also get through. This will hold the tennis ball and string in place. Then tie the string so the tennis ball stays attached to the bag." mean? What piece of cardboard? What does the piece of cardboard look like? Do you mean one of the cardboard wings on the rocket? There was no instruction for the piece of cardboard that the strings pass through. What is the purpose of this piece of cardboard? Please be more clear if you are giving instructions.

Absolutely, just have your parents hold it on the launchpad

We have a sudden rash of water-rockets. I'm guessing it's a school project?
