Creakless slippers

Sally’s invention consists of inflatable slippers that enable people to walk on squeezy floorboards without making a noise. I worked with Sally in identifying how to make the resulting prototype best convey her idea to an audience. Then she gave the invention a new iteration in its design. The final prototype was developed according to her specifications. It is a slipper with an air pillow attached to its sole, and with a pompom at the back that turns green from red when you activate it by pretending to be putting the slipper on – as a way to demonstrate the interactivity of the invention.
