Piston-Fit Drawer

The term "Piston-Fit" has long been used to describe the ideal furniture drawer: smooth-sliding and snug-fitting. With such a drawer, however, air pressure builds up in the cavity behind the drawer as one closes it. This piece harnesses that energy for a humorous purpose: as the drawer is closed, the air is ducted through 2 small holes in the top, which causes the wind trubine to spin. Close the drawer faster and the turbine spins faster. How fun is that! See the video below.
