MLFT : My Little Freezer Tester

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
