Toys from Trash – CD Hovercraft
Make a lovely Hovercraft with an old CD, a balloon, a rubber disc, glue, a needle, a rubber band and an old sketch-pen. Let's watch the video and first learn how to make it.
You need to place an inflated balloon in the center of the CD such that the air escapes very slowly from below. Place it on a smooth surface and give it a gentle push. The CD will skim smoothly on the cushion of escaping air.
Hovercrafts work on this principle. Wasn't that easy to understand? We shall look at a few more Do-It-Yourself 'Experiments' and 'Toys from Trash' in the coming weeks!
