Hi friends,

I do not know about you but I like gadgets. And the more it's useless, the more I like it.
There are many ways to test the safety of a freezer but I decided to make my gadget for that.

It is a kit of 2 parts: a tank and a receiver.
How it works:

Step 1: fill the tank with water. No need to completely fill the tank. 2/3 is enough.
Step 2: put in the freezer until the ice is solidified
Step 3: return the tank into the receiver
That's all.
You leave the kit in your freezer. When you return from your vacation or if you have a doubt, look at the receiver. Two possibilities :
1 / If there is no ice, the ice in the tank has never melted. Good news ! You can keep your food !
2 / If there is ice in the receiver, the ice in the tank has melted, the water has dropped and then froze again. This means that the temperature has been above 0 ° Celsius at a time. Your freezer has failed. Bad news !

I hope you'll enjoy this gadgetissimo gadget !

Bonjour chez vous
