The bassis of science is play. The desire to fly, to visit the moon, to get a reaction from a pleasurable action.

What if I could squish something and trigger an action? How about that something is a balloon.

A pressure transducer attached to an arduino creates the possibility to harness the output of the pressure difference generated from squishing a ballon. If this output gets printed in an LED and the LED gets into said balloon we get: A squishy button!
