Ball Floaters

Float a ball on a stream of air

This is a module consisting of 4 exhibit stations with a central bench. Ball Floaters is extraordinarily simple in concept; a blower moves air through a pipe and out through two or three clear tubes connected with “T”s. Small foam balls can be balanced on the airstream coming out of the tubes, so that they float. With some experimentation, visitors discover how to get the balls to drop down into one tube and pop out of another, to balance more than one on a stream of air, and to balance halfway up the clear tube.

The exhibit is fun, and visitors leave with a sense of how air can be directed and manipulated, and the effect of that manipulation on objects in the path of the moving air.
