... a comedy landmine explosion.
I was, I'm sure, the only person who saw it, as I was in a fairly secluded situation and it was me that both primed it and then set it off.
I was in Castle Church graveyard, cleaning a gravestone for someone*. My intention was that, at the conclusion of the process, I would rinse off the cleaned area. To do this, I took a pressure sprayer full of water, unpressurised, with the intension of pumping it up there, to avoid incidents in the car on the way.
The sprayer is a plastic device and has been subject to sunlight exposure for many years. Pumping it up to pressurise the contents was too much for the 'bottle', weakened by years of UV exposure and it let go very suddenly and dramatically, spraying water and bits of plastic over quite an area - and me.
I wish I had seen it properly...
* The person that I do this grave for lives in New Zealand and I do need to sort out someone else to take it on, as I won't be coming back many more times, I hope. It takes two ten-minute visits per year.
