yeah me too, they seem like they burn really slow!
best explosions i've seen are when my grandpa lights his brush piles on fire!!
he has these 55 gallon drums of solvents from his old paint factory lying around that he didnt want to pay to get rid of, so every year we put like 20 gallons of the stuff on the pile, make a little trail o fgasoline about 30 feet away and drop a match!!
BOOM and a mushroom could and the concussion its fun, then he get to the more dangerous part of throwing kerosene on the places that dont look like they're burning well (aka flames only 2 ft high)
so much fun!
