Code Number: 2C20.20
Demo Title: Atomizer
Condition: Good
Principle: Bernoulli's Principle
Area of Study: Fluids
Equipment:
Beaker with Atomizer Attachment, and Air Hose, perfume atomizers, Ping Pong ball atomizer model, vacuum blower.
Procedure:
Hold the hose at the top of the tube that is coming out of the atomizer and at a 90 degree angle.
An interesting variation is the Ping Pong ball atomizer model. Place the lower end of the clear plastic tube just above the Ping Pong balls and blow across the top of the tube with the vacuum blower. Ping Pong balls will be sucked up the tube and blown out sideways in the vacuum blower air stream.
