A bourgeoisie stove is easily made from a soda or beer can with only a knife and can opener. To begin, obtain a soda or beer can. Then, then remove the top with the can opener. Next, ventilation slots are cut around the base. Four or five are enough, evenly spaced around the circumference. The vents should be inverted V's, like A's without the crosspiece about an inch tall. Use the knife to fold the point in, until it is parellel to the base of the can. The fins provide a space for ashes to fall into, effectively reducing the amount of work required to operate the stove.
