2C20.60 - Magnus Effect - "V" Launcher and Ball

Code Number: 2C20.60
Demo Title: Magnus Effect - "V" Launcher and Ball
Condition: Good
Principle: Magnus Effect
Area of Study: Fluids
Equipment:
Angled Paddle, Ping Pong Balls, Styrofoam balls,
Procedure:
Note: Make sure to put your hand through the cord loop on the handle of the apparatus. This is to prevent the apparatus from flying out into the audience in case inadvertently let go or the apparatus handle slips out of your hand.
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.
