to make the can part poke or drill holes in the top and bottom of the can for air.
then to make the candle you poke two holes in the wax of the main candle with a toothpick, then peel the wax off the birthday candle. t cut the wick of the birthday candle into two pieces about 1cm long then stick them in the holes. light all three wicks put the can over the candle, if the flame go's out then poke more holes in the can. then your done. then you cook your food on the top of the can. i hope you like it.
