How do you explain to a kid how kettle works?

A kettle is a kitchen appliance used to heat water. It is typically made of metal and has a spout for pouring. When you put water in a kettle and turn it on, the heating element inside the kettle heats the water until it boils. Boiling water means the water is so hot that it turns into steam and bubbles. When you pour the boiling water out of the kettle, you can use it to make tea, coffee, or other hot drinks.

Here's a simplified explanation that you can use to explain a kettle to a kid:

Imagine you have a magic pot that can make water hot. When you put water in the pot and turn it on, a little creature inside the pot starts a fire. The fire heats the water until it gets so hot that it starts to bubble and dance. This is what we call boiling water. When the water is boiling, you can pour it out of the pot and use it to make yummy hot drinks like tea or cocoa.
