Put the metal bowl in a larger container of crushed dry ice (sublimation temperature -78C).

One way to make ice without electricity or a freezer is to move to Alaska...put a bowl of water outside...it is -16 degrees F here this morning...wait for the water to freeze into ice...this probably isn't feasible...so another option would be forcing compressed air through a hole in the middle of a pipe causing hot and cold air to flow from opposite ends, a phenomenon known as the Ranque-Hilsch vortex-tube effect.

put water in the metal bowl, put the bowl outside when the temperature drops below 0 degrees centigrade. In the morning...viola!

Fill a bowl half with ice and half with liquid nitrogen.
