How to Make a Thaw Detector for the Freezer

DSC_0991

Have you ever wondered how you would know if the food in a freezer you visit infrequently had thawed and refrozen after a power outage? With this handy-dandy, nifty-thrifty thaw detector in your freezer you won’t have to wonder ever again.

It is simple to make. We found these cups and lids at a salad bar at Kroger.

Fill the cups with water and place in the freezer.

When water is frozen, place a coin on top of the ice and put the lid on.

With this thaw detector, as long as the coin stays on top there hasn’t been a thaw of significance.

My nerdy husband who devised this contraption says, “Coin on top, food’s not slop. Coin on bottom, food is rotten.” If you can think of a better slogan, post a comment!
