This is my lemonade bottle rocket. A great thing on a sunny when your bored.
Step 1: What You Need
1. A foot bike pump
2. A cork (I personally use a champagne cork)
3. A valve from an old bike tyre inner
4. A lemonade bottle
5. A drill (if needed to drill a hole in the cork
Step 2: Preparing the Cork and the Bike Valve
Drill a hole in the cork and stick in the cut out bike valve.
Step 3: Preparing for Take Off
Fill up the lemonade bottle to it is about 1/3 full then stick in the cork with the valve in it. If the cork doesn't go in, use a knife to trim it.
Step 4: Attaching the Bottle to the Bike Pump
Attach the bottle to the bike pump, lean the bottle on a steep ramp and pump.
Step 5: Enjoy Doing It Over and Over Again
