Bernoulli's principle: Ball suspended in air stream.

2C20.30 • C+25+5

diagram for demo

Bernouilli's Principle: Ball suspended in air stream. The styrofoam ball can be balanced on air from the wind tunnel. Or, the ball can be balanced on air from a compressed air hose and nozzle. (Or the attachment in C-25-17 can be used).
