..... and how do you know when you were away how long was the power out and is it safe to eat the stuff in your freezer?
A tip from our local Hydro Company
For cottagers or people when they go away on vacation and are not really aware when the power goes out how long it has been off.
Get a small container of water and put it in the freezer. Once it is frozen, put a coin on top. If you go away on vacation and your hydro goes out long enough that the ice starts to melt, when you come home if the coin is no longer on top then most likely your food that was frozen also thawed and is not good to eat.
