A mortsafe is a metal cage that is fitted over the grave of the deceased, to prevent grave robbers digging up the body and selling it to medical schools for research... but I digress.
For the individual concerned that an arch-nemesis might wish to urinate upon his/her grave after death we have come up with an electrified mortsafe, to dissuade such err... "precipitate" action.
A couple of sensors to detect the sounds of urination; maybe one to pick up the presence of urea in the liquid and a shocking realisation descends upon the miscreant micturator.
Also useful to prevent dogs and monkeys performing the same evil deed upon your final resting place.-- UnaBubba, Apr 10 2012 ...and dancing. We must prevent the grave dancing.Welcome back.-- 2 fries shy of a happy meal, Apr 10 2012 If you're getting 415 volts up your wedding tackle there is little question whether you'll be dancing.-- UnaBubba, Apr 10 2012 This would require a continuous stream would it not? If one has learned to relieve themselves in pulses it may not work...-- 2 fries shy of a happy meal, Apr 10 2012 If you're willing to take that chance with 415 volts of 3-phase power, go ahead...-- UnaBubba, Apr 11 2012 Three phase!? Well, say no more.-- 2 fries shy of a happy meal, Apr 11 2012 OK.-- UnaBubba, Apr 11 2012 //uric acid// sp. urea. Birds excrete uric acid - it's mostly insoluble, and accounts for the white part of their droppings. A human who pi^Hasses uric acid is pretty messed up down there.-- spidermother, Apr 11 2012 Fair enough. I've never actually studied the composition of human urine, I have to admit.-- UnaBubba, Apr 11 2012 study? no. taken? often.-- po, Apr 11 2012 You know me too well, [po].-- UnaBubba, Apr 12 2012 random, halfbakery
