re: #286 thedopefishlives

The first time we did a fireworks show, it was with the cheap cardboard mortars that you can buy at fireworks stores of questionable legality. One of the tubes blew out and launched its projectile directly at our audience.

The very next year, we were professionally trained by the Pyrotechnics Guild and purchased a set of HDPE mortar tubes. No more blowouts or near-misses.

Speaking of which…
