Defrost Detector
When your freezer derails, it may take a while to notice it. Sometimes too. To avoid food intoxitations, here's a tip. Hack your freezer!
Components and Tools Needed:
Tools:
- cutter
Materials:
- 2 plastics bottles
- food coloring
- water
Construction
If you have two identical bottles, cut into 2 parts.
Otherwise, cut the top of the bottle and the neck. You now have a stand for your bottle.
Put a few centimeters of water in the bottle, and a few drops of food coloring.
Put the bottle in the freezer. When the bottle is frozen, return it.
Finish
If the water is in the back of the bottle, you have a problem !
