Check out this video of the fish tank doubling as a fryer. Maybe the fish will be smart enough to not go over the water into the hot oil… I don’t mind the video but the food cooked in that environment just doesn’t seem too tasty…
See, you have this aquarium with real live fish, and then, sitting right on top, is piping hot oil (163 Celsius) that is actually used to cook food. Since the water and the oil don’t mix, all the fish have to do to stay alive is not venture into the hot oil on top. What’s more, fallen crumbs from the frying process fall into this aquarium, serving as fish food.
