Bernoulli Counter

See the Bernoulli Principle in action!

Suspend light-weight spheres in mid-air while learning how something as heavy as a jumbo jet is able to fly as though it’s lighter than air!

Intended Use

User approaches the exhibit and selects a colored Ping-Pong ball. The user presses the green button to activate the airflow for 10 – 17 seconds (0-128 second range) and then attempts to suspend the ball in a small stream of air, finding the right position.

Try to toss a ball and ‘catch’ it in a stream of air, or suspend a ball in each air stream simultaneously before the timer runs out. Rotate the pendant to demonstrate how the Bernoulli Principle acts on objects in motion.
