This is how they do hot tubs down under. This homemade contraption was built using a large storage container, an LP gas bottle, stainless steel tubing, polystyrene packing material, and some corrugated iron. You can spend however much you want on a hot tub with a built-in HDTV or 1,500 jets or whatever, but it still won't be as badass as this thing with its little monster burner. Amazing. [Make]
