Balloon Rocket

For Transfiguration this week, the Hogwarts Students get to turn an ordinary old balloon into a rocket!

I love this fourth of July inspired tube for the balloon from Light Bulb Books!

Here are the instructions from Science Bob. 

1 balloon (round ones will work, but the longer "airship" balloons work best)
1 long piece of kite string (about 10-15 feet long)
1 plastic straw

Tie one end of the string to a chair, door knob, or other support.
Put the other end of the string through the straw.
Pull the string tight and tie it to another support in the room.
Blow up the balloon (but don't tie it.) Pinch the end of the balloon and tape the balloon to the straw as shown above. You're ready for launch.
Let go and watch the rocket fly!
