I was reading a similar post on another forum when I was reminded of this long ago disaster. I’ll post it here since you guys are friendlier. This happened in my late teens so I should have known better.
My parents threw out an old dresser so I took it to the burn pile. Hmm, sez I, this could be more fun then just a bonfire. Instead of just burning it I poured a little gasoline in each of the drawers except the bottom one. Closed em up real good. Then I lit a firecracker with a long fuse, dropped it in the bottom drawer and slammed 'er shut. What I anticipated was a delay followed by a POP followed by the dresser vigorously burning down. What happened was I was instantaneously wearing 4 flaming drawers in my lap while the casing flew backwards with a healthy whoosh! A few seconds later the firecracker finally went off.
Within a few months I has hired at NASA. Coincidence? I think not. In my first year I spent some time with assisting my supervisor giving safety demonstrations. During one of them things went awry and he nearly shot someone in the audience when he didn’t read all the instructions. I felt better after that.
