Story Synopsis
A refrigerator feels like it makes cold, but it really moves heat. This story explains that idea in a clear, gentle way. Miluna shares that inside the fridge is a special fluid called a refrigerant. It travels through tubes and changes from liquid to gas and back again. When it changes, it can absorb heat from inside the fridge. Then it travels to coils on the back or bottom, where it releases that heat into the room. A compressor keeps the cycle moving. The tone stays friendly and simple, helping kids see everyday appliances as quiet science helpers. Curiosity stories like this build confidence and love for understanding the world.

In One Glance
Refrigerators cool by removing heat, not by ‘creating cold.’ A refrigerant circulates through tubes. Inside the fridge, it absorbs heat as it changes state. Then it moves to coils outside, where it releases that heat into the room. A compressor keeps the refrigerant moving through the cycle. The story explains the process gently and helps kids see everyday technology as understandable.
