Make+a+Hovercraft

Hovercraft ride on top of the water by using jets of air to propel them. You can make a simple hovercraft to see how it works.

To make a hovercraft you need:
 * a large balloon
 * two old CDs
 * tape

Directions:
 * 1) Tear off pieces of tape and stick them on the edge of the table you are working on, ready for use.
 * 2) Put the two CDs together to make your hovercraft platform.
 * 3) Poke the nipple of the balloon through the hole in the CDs.
 * 4) Blow up the balloon and hold the valve shit with one hand.
 * 5) With your other hand, loosely tape the balloon to the CDs.
 * 6) Keep holding the balloon valve shut and place the hovercraft close to the floor.
 * 7) Let go of the valve and your hovercraft will glide just over the surface of the floor.
 * 8) Balloons can be all sizes, so if your hovercraft doesn't work, experiment. Add a paperclip to slow down the airflow out of the balloon, or use three CDs, not two.
