ELI5: Explain Like I'm 5

Icyball

An icyball is like a magical container that keeps the food or drinks inside it cold for a long time without needing electricity. It looks like a big metal ball with two sides, one of which you can fill with ice while the other side has the food or drinks. When you put ice in one side and close the icyball, the heat from the food or drinks is absorbed by the ice, which melts slowly and keeps everything inside cold.

Think of it like a superhero cape that protects your food and drinks from the hot weather outside. Imagine you are having a picnic in the park on a sunny day, and you bring a lot of cold water and sandwiches. If you leave them outside, they will become warm and not taste as good. However, if you put them in the icyball, they will stay cold even if the sun is shining!

Icyballs were invented a long time ago when people didn’t have electricity in their homes. They used to keep their food cold with iceboxes, which were big wooden boxes filled with ice. Later on, icyballs came along and were much more convenient to use because they were portable, lightweight, and you didn’t need to buy more ice regularly.

Overall, an icyball is a fantastic invention that helps keep your food and drinks cold, just like magic!
