A Bridgeport, Connecticut woman was seriously hurt after lighting a stick of dynamite she thought was a candle, police said.
It was actually an M-1000, a "quarter-stick" firework -- which isn't actually a quarter stick of dynamite, as it doesn't use nitroglycerin. It's much less powerful than dynamite.

I think anyone can see why one might mistake it for a candle in the dark.
