Using just your breath, can you move a Ping-Pong ball from one cup to another?

The Setup:

Form two lines.

Each team member has a styrofoam cup. (Small cups work best -- just remember to hold them steady.)

Drop a Ping-Pong ball into the first cup.

Without touching the ball or "pouring it" move the ping pong ball from cup to cup.

The Trick:

Take a deep breath! Now blow down the side of the Ping-Pong ball closest to you. Watch the ball jump up and into the other cup.

Why It Works: Blowing down the side of the ball creates a stream of compressed air. This stream of air pushes the ball up, forward, and into the second cup.

Hint: Have each kid practice before racing.
