Greetings While on an elk hunting trip in the mountains we awoke to roughly 2 feet of snow. Everyone wanted coffee and nobody had brought any conventional coffee tools. A cowboy boiled water in an aluminum pot just dumped coffee grounds in the water. Naturally a lot of those grounds floated near the surface. He then simply touched the bottom of the pot to the snow and almost instantaneously the grounds, all of them, shot to the bottom. He was then able to pour off the liquid with almost no grounds in it as long as the pour was slow and smooth. Was this simply some sort of thermal reaction or was there an electrical component?
