There is a glitch that lets fire charges go through a 1-meter wide wall when shot out of a dispenser. Make a wall out of non-flammable material. Leave a 3 space gap. Then make another wall. In the gap, put a single block located right beside where you want the dispenser. Place a dispenser so it is facing the inside wall and there is no space between the dispenser and the wall. Place redstone on the block that leads to the dispenser [you have to use a repeater]. Start building the inside. You need to surround a piece of netherrack with iron bars. Make sure the floor is not made out of any wooden materials, wool or carpets as they will burn. You may decorate this any other way but place a button where the redstone signal would receive the input. Then, place multiple fire charges in the dispenser [they don't have any other important use]. You will have to kill blazes and creepers/ghasts and mine coal or kill wither skeletons to make them so they are hard to make but are worth the trouble.
