Simple to use, but full of amazing air science. Just blow into the wooden-train pipe and watch the ball levitate in midair. It looks like magic, but of course it's better than that - it's science!
The ball becomes trapped in the fast moving air-stream because of Bernoulli's principle. The same principle used in aircraft design to create lift. As long as you keep blowing, the ball will keep hovering. How long can you keep the ball afloat before you run out of steam?
Presented in a train shape in various bright colours, the Floating Ball Game will amaze anyone, from your parents to your best friend to your science teacher. A fun demonstration of air principles for science parties or classroom activities.
What You Get
Floating Ball Game. Consists of 1 wooden train ball blower and 1 foam ball. Train blower measures 10cm in length. Train colours vary. A random colour will be selected for your order.
How Does It Work?
Bernoulli, an 18th century Swiss mathematician, discovered that the faster air flows over the surface of something, the less the air pushes on that surface. Thus, the air pressure on the object is lower than usual.
Blowing into the tube creates fast moving air around the sides or the ball. This moving air is at a lower pressure than the surrounding stationary air. Look closely, and you'll see the levitating ball wobble as it attempts to leave the area of low pressure but is forced back into the air-stream by the high pressure surrounds.
