Ground bottle rocket plane
Step 1: The Soda Bottle
Firstly get a soda bottle and drink or empty the soda inside.
Note: Any soda bottle works, we will be using a 20 oz bottle in these instructions. DO NOT USE any other type of bottle, soda bottles are meant to handle a good amount of pressure for the carbonation.
Step 2: Hammer
Find a hammer and a nail, any sizes are acceptable.
Step 3: Hole
Remove the cap from the bottle and nail a hole into it. It is best to get the hole as centered as possible.
Step 4: Tape
Find a type of strong tape, cut off a piece. Get a small pin as shown and use the pin to make a very small hole in the tape.
Step 5: Verify
Make sure the tape will be able to cover the cap.
Step 6: Wrap
Line up the tiny hole with the hole in the cap and cover the cap with the tape. Then screw on the cap onto the bottle.
Step 7: Bike Pump
Locate a bike pump that has a pressure reading, place the bottle rocket next to the bike pump. Feel free to add any wings or anything you so desire.
Note: The rocket shown was designed to take off from the ground like an airplane.
Step 8: Connection
Place the bike pump pin inside the soda bottle.
Step 9: Pump
Start pumping the bike pump until the pressure reading is around 50 psi.
Note: Don't exceed 50 psi.
Step 10: Release
After the pressure is around 50 psi, move the bottle off of the bike pump pin and release. The bottle will rocket away!
