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!  See the video on Utube.
