lol noted.Just a small metal coffee can. No holes, charcoal you want to smolder not burn up too quick or get too hot. It really does work great. My hands have been so cold duck hunting I couldn't get the safety off the gun.
Disclaimer: do not use lump charcoal. Only briquettes. The lump charcoal turns your heater into an inferno. Although you can cook a few duck breasts on it this way with tin foil.
