SHRINK AND SINK - ENGLISH - 14MB

This is a new kind of Cartesian diver. Fill some ball bearings in a balloon to make it heavy. Inflate a little air and then tie its mouth. The balloon must just float in a mug of water. Then place the balloon in a 2-Liter water bottle filled to the brim. Shut the lid. On pressing from outside the balloon (being a closed system) will shrink, the buoyancy will reduce and it will sink. On releasing pressure it will float to the top. http://arvindguptatoys.com/toys/Shrinkandsink.html This work was supported by
