The other day I experienced a discharge of static electricity. It was unusually strong, so strong that it almost hurt. I would like to hear your answers to how such a strong static charge could have built up. Was it just a coincidence, or was it something I did that enabeled an unusually strong electric charge to build up?
At the moment, I was sifting whole bran rye flour using a wooden framed sifter with a metal net. The flour fell on to an enameled metal baking plate on a metal kitchen counter top. As I touched the flour on the baking plate, there was quite a powerful discharge. As I sifted I noticed that the flour stuck to the metal net of the sifter, so it seems to have been a static charge involved there as well.
