Today's Topic: Air Movers (and the Bernoulli Principle!)
Supplies:
plastic drinking straws
hair dryers (make sure they have a cool setting or at least a "cool shot" button that can be taped down)
round, lightweight balls (ping-pong, styrofoam, even plastic eggs work in a pinch)
a variety of things that can (and can't) be pushed around by air blown through a straw (we used pom-poms, rubberbands, toy cars, drink bottle caps, shapes cut out of foam sheets, bouncy balls, feathers, wooden blocks, buttons, packing peanuts)
buckets (optional, but as you'll see later, they can be lots of fun!)
