about 1300-2400 BTU/lbBut how many BTUs did the stove extract from the grenade?
I accidently threw a two pack of Surefire 123A batteries in my stove in the shop. The first one went off after about 30 minutes.........the second a couple of minutes later. It was pretty darned loud. About as loud as a .22LR from a rifle. Scared the s_ _ t out of me but did get the fire going pretty good. I can only imagine what a grenade would sound like and I am not sure my stove would survive the blast.
I'm sure a sphincter or two went off too! :-)Nothing like a nade going off inside "your" house! Lotsa fun there!
