Interesting weekend, all things considered, but not necessarily in a good way. I have now joined the serried ranks of the fools who put complex electronics through the washer. In my case, my cellphone. *argh*
The real source of damage, however, was at archery. Dry-firing a bow (loosing the string without an arrow on it) is really not smart, especially when the weapon in question has a draw weight in excess of 35lbs. Without an arrow to fling away, all the energy that would have gone into the shot is instead dissipated into the fabric of the bow, causing a lot of vibration and, not infrequently, a lot of damage. At my first competition, I watched an accidental dry-fire (the arrow fell off the rest while the archer wasn't watching) literally rip apart a bow. Fragments of carbon-fibre and various wood laminations were thrown halfway to the targets (about twenty metres, for reference), and the archer in question was left holding a pressed magnesium handle, looking mildly stunned and very, very unhappy.
I dry-fired my bow by accident on Saturday. Checked my stance by drawing it up, and lost my grip on the string at the worst possible moment. It normally makes a nice concise thump when fired: this time it twanged with a rather unpleasant note. It was only after I'd dismantled the entire thing and checked it thoroughly for damage (none, thank goodness) that I noticed the impressive friction-burn/bruise the string had left as it rebounded off my right forearm.
It's really quite painful if I forget about it and try to do something with it, but so long as I'm careful it's alright. I've had worse. But it nearly cost me a lot more than I could pay. If that dry-fire hadn't glanced off my arm, and all the energy that left a 10x5 cm bruise on my arm had gone into the bow instead, I might have been looking at a minimum of £200 to get the bow serviceable again.
