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!
