Here's an easy ten minute rocket. My younger brother and I have lots of fun making this. We used an an inner tube, drill, drill bits, a rod, duct tape, a plastic soda bottle, wood, metal hammer, pvc pipe, and a utility knife.
Step 1: Step 1
First, start with an inner tube, drill, drill bits, a rod, duct tape, a plastic soda bottle, wood, metal hammer, pvc pipe, and a utility knife.
Step 2: Step 2
Cut the tire nozzle out of the inner tube.
Step 3: Step 3
Cut the rubber from the nozzle.
Step 4: Step 4
Ask your mom or dad if they would have a plastic cork; you can also ask your friends' parents to save corks for you. Don't use a real cork made out of cork because it will fall apart. You might have to cut the plastic cork if it's too long.
Drill a hole in the cork to fit the tire nozzle.
Step 5: Step 5
Get two blocks of wood (2x4's). Drill a hole in the wood. Put the tire nozzle in the hole of the cork. Take a rubber mallet and just tap the nozzle into the cork.
Step 6: Step 6
Get a plastic soda bottle, a short piece of pvc pipe, and a roll of duct tape.
Cut a 3" piece of pipe and tape it to the bottle.
Step 7: STEP 7
Use a piece of copper pipe or a rod. Pound the rod or pipe in the ground.
Take the rubber mallet and tap the plug in as in the picture below. Slide the bottle on to the pipe.
Step 8: STEP 8
Use an air compressor. Find a tire air filler and fill the bottle with air. We fill our bottles to about 50-80 psi. While you're filling the bottle with air, it will take off!
Try not to lose the cork so you can re-use it!
