Condition :	Good
Principle :	Bernoulli's Principle
Area of Study :	Heat & Fluids
Equipment :	Angled Paddle, Ping Pong Balls, Styrofoam balls,
Procedure :	Put a ping pong ball in the groove and throw to show a curve ball. Styrofoam balls will also work very well and will travel farther than the lighter ping pong balls.
