Years ago, before I was wise, I was attempting to light a woodburning stove. Unfortunately all the wood was wet, so I had the brainwave of throwing in some petrol (I had only ever had fun experiences with petrol up to this point).
After pouring in 1/2 litre of petrol, staying low, I gingerly held in a lit match at arms length.
I was literally thrown across the room by the force of the explosion, the room filled up with soot and there were huge flames coming from the chimney. It wasn’t even my house.
You live and learn. :-)
