Make a lovely Hovercraft with an old CD. 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. www.arvindguptatoys.com/toys/hovercraft.html This work was supported by IUCAA and Tata Trust.
