Rly. I still have scars and pleasant childhood memories from the firecracker wars of East Texas...stepping on the bottle you launch the bottle rocket from isn't a problem for shod folk. Also always throw the firecracker/m-80 with an open palm so you don't blow your fingers off and interrupt the festivities. Best to wear a leather glove on the hand you use to load the bottle rocket rifle. If somebody shoots you with a pellet gun, you take it, you keep it no matter what their momma says. There is nothing quite as funny as pitching a dozen bundle of lit roman candles into the secret hideout. an actual 1/4 stick of dynamite is way more powerful than an m-100, neither of which should be thrown by a hand you want to keep. Model rocket engines can exceed the speed of sound when launched from a suitable piece of pipe. "in"flammable does not mean "will not burn" oops. Clean up before your parents come home; fresh fertilizer tends to overcome the smoke odor. Sand the char off the siding before you paint. etc.
you ever launch CO2 cartridges?
