Evaporative cooler

An evaporative cooler is like a giant sponge that's blowing cool air at you.

You know how when you come out of the pool, it feels cold because the water on your skin is evaporating? That's basically the same way an evaporative cooler works.

The cooler takes in hot and dry air from the room and puts it through a wet pad or sponge. The pad or sponge is soaked in water, and as the hot air passes through it, the water evaporates and cools the air down.

Then, the cooler blows the cool air back into the room. So, the air coming out of the cooler feels like a refreshing breeze.

It's important to note that this type of cooler works best in dry areas. The reason is that high humidity can make it harder for the water to evaporate, and that means the cooler won't be as effective. So, if you're in a place like Arizona, an evaporative cooler might be a great choice!
