Only one, Brit, please humor us....?;-)
Probably making a petrol bomb when I was a boy and getting my eyebrows burned off.Then there was making a muzzle loading cannon out of old pipe, pouring gunpowder out of fireworks down the muzzle, then loads of nails and nuts and bolts, then firing it at an old abandoned car. Now that WAS fun.:mrgreen:
But if you hadn't how would have known about all the things you were doing incorrectly.Probably getting married!![]()
