Sorry guys, I’ve got to comment on this one. [tylin] sent in this “DIY SCUBA” youtube video. These guys used a home shop air compressor with a particle filter so they could “SCUBA dive”.

This time he’s come up with a wind-powered pump to move air through a hose to a modified scuba mask ... And they work great. The air compressor is taken from a car and the base of the wind ...
