Answer 1

The boiling point of the water increases with increase in pressure.
so the bubble start from the bottom at the sauce pan where the nail or coin arranged. In geysers, boiling begins near the bottom and the bubbles that are raising above push the water out starting eruption. This is the laboratory demonstration of working of natural geysers
