The “Do Not Freeze” List
To keep your family safe and your appliance intact, never put these items in the freezer:
1. Glass Bottles (Liquids)
The Danger: As explained above, water expands. Glass breaks. The Exception: Some thick glass jars (like Mason jars) are “freezer safe” if you leave headspace (room at the top) for expansion. But standard soda or beer bottles? Never.
2. Canned Goods
The Danger: Just like glass, metal cans can burst if the contents freeze and expand. This creates a sticky, frozen mess that is hard to clean and can damage the freezer liner. The Fix: If you want to freeze soup or fruit from a can, transfer it to a plastic freezer-safe container first.
3. Carbonated Drinks (Even in Plastic)
The Danger: Carbonation adds gas pressure to the liquid pressure. Even plastic bottles can bulge, deform, or burst open the moment you open the cap, spraying sticky soda everywhere (or hitting you in the face).
4. Hot Food
The Danger: Putting a hot pot of soup directly into the freezer raises the internal temperature of the appliance.
- Risk 1: It can partially thaw the food surrounding it, leading to bacterial growth.
- Risk 2: It forces the freezer motor to work overtime, potentially burning it out (which might explain the burnt smell in some horror stories!).
- Risk 3: Condensation forms ice crystals, leading to freezer burn.
5. Eggs in the Shell
The Danger: The liquid inside the egg expands, cracking the shell. While not an “explosion,” it creates a messy, bacteria-prone leak. The Fix: Crack the eggs into a tray or container before freezing.
6. Aerosol Cans
The Danger: Whipped cream cans or cooking sprays are under pressure. Freezing them can cause the canister to rupture.
