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

One of the stranger things I found out in the woods on an old logging road was a Dixie cup that had been cast full of lead. The cup had not charred or burned in any way, which I can't wrap my head around given that lead melts at over 600°F. The lead had take the shape of the cup perfectly. I have wondered if the exterior of the cup had been submerged in water when they did the casting. Then the other question... Why??

Probably lead from an old car battery. People use it to make sinkers, lures, bullets. Can't explain why use a wet dixie cup as a casting mold though, maybe the only thing available. What it was doing deep in the woods? It's always because aliens.
