Bottle Rocket




Posted in OutsideRockets

Introduction: Bottle Rocket

shooting a bottle with compressed air

Step 1: Drill a Hole in the Bottle Cap

insert the drill bit into the drill and drill a hole in the center of the bottle cap so the the valve will fit in nicely.

Step 2: Push the Valve Through the Cap

make sure the valve fits snugly into the bottle cap, and if it does, then pull on the valve until it cant come out through the top of the bottle cap.

Step 3: Get Ready to Pump

hook your pump onto the tire valve so that it fits nicely, and then screw the bottle onto the cap. you are now ready to start pumping the bottle.

Step 4: Shooting the Bottle

pump the bottle to about 70 psi (no more than 100) and remove the pump. hold onto the bottle cap and quickly twist the bottle. it should shoot pretty far. have fun!
