You have to see this video! This is a restaurant in Japan that has a goldfish tank - INSIDE THE DEEP FRYER! And the goldfishare actually alive and well, swimming around totally oblivious of the 162° C hot oil floating above them.
The reason why this is possible is that oil floats on water. The burning hot oil therefor floats on top of the water where the goldfish is. So as long as they don't try to "jump" out of the water, everything is fine. They can live inside an active, working deep-fryer for 5-10 years! The bonus is that all the crumbs and leftovers from whatever is being deep-fried sinks down to the goldfish. Just amazing!
