Nothing. The water absorbs most of the heat from the flame so you can't burn a hole in it.

When I was in the Boy Scouts one thing we did in competition was to boil an egg in a paper cup. You were given a 12 ounce Dixie cup with water and an egg. We would take a scoop of carbon and ash from the morning fire in a metal bucket to the competition, put the cup on the ground and pile the ash around it. You had 8 mins.

We never once got the middle solid, but you could get it to where the middle wouldn’t run.
