Still have all of my fingers!
We did have one of the big cannon shells detonate still in the tube, didn't even pop like they're suppose to, which I've had happen before, this one just exploded. Almost knocked me back, ears instantly rang, scared the hell out of me, just like a real bomb went off... Wait, it sorta was... The whole shebang took a little long though, started 8:30, finished at 10:15.... Next year we probably slim it down, more higher-end stuff, and less 'filler' smaller type stuff.
Some tips, don't ever hold that 'Laser Candle' you'll be covered in ash... And always look for "legal limit" 500gram stuff. Definitely worth the premium.
