Introduction: 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!
Step 1: Components and Tools Needed:
- 2 plastics bottles
- food coloring
Step 2: 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.
Step 4: Finish
If the water is in the back of the bottle, you have a problem !
