Introduction: Tennis Ball Bottle Rocket by Jessedarrencorey (tm)
You put some bottles with a tennis ball in it and a garbage bag and shoot it. Get ready to learn how.
Step 1: Materials
The materials for constructing a bottle rocket include:
- 4 2L Soda Bottles
- Duct Tape
- Tennis Ball
- Box Cutter
- PVC Pipe
- Garbage Bag
Step 2: Cut Wings
Cut three identical wings out of cardboard and tape the to the bottle with water. (see step 6)
Step 3: Setting Up Capsule (top)
Cut off 2 inches from top of bottle, then tape the rest of that bottle to the midsection of two other bottles. Make sure you round the end of the freshly cut bottle to ensure maximum torque.
Step 4: The Parachute
Construct a parachute. How you ask? Well its simple, cut a circle out of a garbage bag that has a diameter of 4.2 feet. Next cut 6 slits around the outside of the garbage bag circles. Next, tie 6 pieces of string into the 6 slits and attach the other end of the string to a tennis ball. Tape the string to the tennis ball and before you know it, you'll have a functioning parachute.
Step 5: Setting It Up So the Parachute Releases
blow up a balloon with 4 solid blows of air. Tape that balloon to the end of the capsule. The balloon should also taped to a harness which can be constructed from the base of a 2 liter bottle, about and inch and a half from the bottom.
Step 6: Finishing Up
While finishing your rocket, a few more things must be done to ensure total domination. Take a whole 2 liter soda bottle and fill it half way with water. Attach the wings you constructed in step 2 to this bottle. Turn this bottle upside down. Inside the capsule, place 4.167 inches of PVC pipe (which can be cut by string) to the base of the final water bottle which has the wings attached to it. Place the tennis ball on the end of the pipe with the parachute attached and cover it with your capsule.
Step 7: Victory Celebration
It is key to make it know to the people to whom you are competing that you are the best and have constructed the best bottle rocket. First, begin by laughing at the other groups failures, then get with your group and simultaneously mock the other groups. Finally, when you receive an A for your project, print out your powerschool page and tape it to the head of the idiot sitting next to you whose rocket ended up in a beaver dam, 2 miles due east of the launching location.
