An experiment in aerodynamics with Kennedy Space Center

Dee Maynard from The Kennedy Space Center joined GDL once again to give us another fun science experiment to do with our kids.

SAINT PETERSBURG, Fla. — Dee Maynard from The Kennedy Space Center joined GDL once again to give us another fun science experiment to do with our kids. Today, we learned a lesson in aerodynamics. KSC says Bernoulli's Principle states that fast-moving currents generate low pressure zones, providing lift. The curved shape of the ball allows this current to pass evenly on all sides of the ball, keeping it in place. This is one reason curved surfaces are more aerodynamic than flat ones. Rockets and airplanes are designed with lots of curves because they need to pass through the atmosphere. In space, it really doesn't matter what shape they are because space is a vacuum – that's why satellites come in so many different shapes!

Materials needed:

• ping pong ball

• Styrofoam or other lightweight ball

• blow dryer

• bendy straw
