A cold spoon sticks to the bottom of a boiling pot. It does not matter what material the spoon is made of, plastic, steel or porcelain, a force pulls on the spoon at the bottom of a metal pot with boiling water, over a stove.
Negative temperature particles on the cold spoon attract positive temperature particles on the boiling pot.
Try it; from that part in all of us, part Greek.
Note: Hot pot, cold spoon.
