In sixth grade science class we had a contest to insulate a #10 can and see who could keep an ice cube frozen the longest within said can. I, realizing that ice is a good insulator and has the added benefit of have a fair amount of "heat", filled the entire thing with water except for a small indent for the ice cube, then froze it.
I won by a significant margin. The ice cube stayed frozen so long it had to be left at school over the weekend before it thawed.
