You provide the fast moving air, and we'll take care of the rest! You can easily demonstrate the unexpected effects of low air pressure with an electric leaf blower or vacuum cleaner (exhaust mode). A fast stream of air across the top of this fascinating device reduces air pressure in the tube. As a result, ambient air pressure propels the ping pong balls upward, in apparent defiance of gravity! Students at all levels will marvel! Instructions included and available online.
