Make a Duck-Blind Heater
Here's a simple project to keep you warm on your duck hunts this fall. Get a No. 10 can with one end removed (available free from restaurants and institutional kitchens). Use shears to cut a 2x2-inch draft opening on an edge of the open end, and punch six small hot-air escape holes in the closed end. Place it open end down over a can of Sterno. The stove will radiate a relatively smokeless heat.
