Good Morning Tappers,

For a Bernoulli demo, it's hard to beat an electric leaf blower.

I got my hair dryer from target several months ago when one of our
retired
teachers requested a hair dryer for his Bernoulli's demo. There are a
lot of
brands and options. I picked one which has the same functions as you
described: high power and heater can be turned off. I just tried the
dryer
with two ping-pong balls. You need practice a little bit then can make
the
balls up in air for a couple of seconds. The dryer's brand is CONAIR,
the
model is 1002DB. I believe you can find better ones, but need more
patience
to look around.

Good luck.

I am forwarding this request from one of our faculty:
