I've used this idea for years and never had a bear come in that quick. Look for one of the sterno stove tops.All it is is a metal ring that fits on the top of the sterno can so you can place a can on top of it. This helps channel the heat up to the bottom on the burn can. I always use a small Planters peanut can that I've burned the label off of. You don't want that smell ruining your hunt. I pour about an inch of honey into the bottom and let it burn. The honey will boil and get real think and puff out whiffs of burnt honey. Only problem we've had in the past is yellow jackets coming around after the honey has cooled down. Watch out!!!
