Homemade Entropy Detector

easy to make, just put several kinds of beans in a lidded glass jar. then shake it whenever coincidences cause you to suspect entropy is dropping. Mycroft, who probably invented this, gave one to Thursday (in Lost In A Good Book by Jasper Fforde) because someone was trying to kill her using coincidence...such as lightening striking where she stood, a stray bullet hitting her, stuff like that. she had merely to check to see if the beans formed patterns...and if so, run like hell! this doesn't mean low entropy is bad, you might check to see if you should buy a lottery ticket, for example! and of course, usually, a coincidence is just a coincidence.
