3. The ice pop tip
Lay an ice pop horizontally over another object in the freezer. If it is still lying straight when you arrive home, the freezer has been working fine. If it has sagged over the edges of the other object, you’ll know the freezer has defrosted a little. If the ice pop has bent all the way down to lie flat against the sides of the other object, you’ll know it turned to liquid.
4. The water bottle tip
Fill a bottle halfway with water and freeze so the ice is on the bottom, then lay the bottle on its side. The ice will stay in the same formation as long as the freezer keeps working. Hint: You can do the same with ice cream. Eat half, and then lay the tub on its side. Yum!
