Just be careful with them, had a 4th of July party at the house a bunch of years ago now where a mortar was improperly lit and it went off before the person lighting it could get back. It launched and ricocheted off his forehead took over 100 stitches to close him up, the only thing that saved his eyes is that he normally wore glasses. Of course he shouldn't have had his head over the mortar tube to begin with but s**t happens quick.
