>I am looking for the make and model number of a heavy duty hair dryer for
>the ping-pong ball/ Bernoulli effect demo. I have seen/heard of some that are
>powerful enough even to "levitate" two balls. Variable blower and heater settings
>would be great ( best with the possibility of turning the heater entirely off).
