Try a SOBE bomb. Filla Sobe bottle 2/3 full of gas, put a pin hole in the cap and put back on the bottle, place in the fire, and after about 2 minute the gas will start to boil and put off a mist which will ignite. Then after about 15 more seconds the pressure will overcome the cap and blow a 30 foot fireball in the air!!!
KIDS don't try this!!!! Have to say this, nobody try this,except me, this is dangerous!!!
