I remember when one of my sons was a teenager. They took all their dud fireworks, placed them in a mound and set them ablaze. He was dang lucky he only suffered the loss of his eyebrows and eyelashes and a little bit of time spent at the doctor checking out his eyes. Needless to say he still does a lot of fireworks but he is extremely cautious about it now, thank goodness because in our state as long as it's the day before, of or after a holiday you can blow up as many fireworks as your heart desires....which ultimately though gets tiresome after awhile when there isn't to many holidays you can just enjoy some peace and quiet.
