How does a refrigerator work?

Ever wonder how your milk stays chilly? It's all about a super-cool journey happenin' inside! See those curvy Inside Coils? They act like a giant vacuum, suckin' up all the warmth from your food and keepin' it inside the pipes. That heat makes the Coolant Liquid get so excited that it turns into a floaty gas and starts movin' along. Then, the Compressor—that cute round guy at the bottom—gives that gas a HUGE squeeze! Squeezin' it makes it super hot, like how your hands get warm when you rub 'em together really fast. Next, it travels through the Outside Coils on the back of the fridge to dump all that heat out into your kitchen. Phew! Finally, it shoots through the Expansion Valve. It's like a tiny spray nozzle that turns it back into a freezing cold liquid so it can go back and do it all again! AMAZING! Tiny Concepts.
