I went out to the shop today and used my dipper and a torch, I found out some pennies melt at low temp and some do not. But this is the weird thing...I tried to remove one of the pennies with a steel screwdriver, and the dipper started burning with a white light like magnesium, then it started making large amounts of fluffy white stuff like spiderwebs, then became sulfur looking with the white still burning...There was white spiderwed crap floating all around my shop. Very, very weird...can anybody tell me what happened?
