Summer is rapidly gaining momentum and carries with it a permanent heat. If you have no air (and he, by the way, is eating up a lot of electricity), and stoically endure the summer heat and have no desire to try to make their own air cooler. Their operation principles are universal, and the necessary materials will likely already have at home.
Air from the milk carton
This video shows manual and full parts list needed for the project.
Air conditioning copper tube
A more advanced design that uses a small electric pump circulator for aquariums. In this case, he runs water through a copper tube where it effectively gives the accumulated heat.
Small countertop cooler
This small cooler consists of a plastic container, 9-volt battery and computer fan. It blows out air in all directions, but it can be modified so that air was only one way.
Air foam
The foam is great for creating a cooler, because it has good insulating properties and it is easy to cut (it costs almost nothing). This video shows you how you can cool the air with it.
Air from the fan
You’ll need a fan and two plastic bottles. Cut the bottoms of bottles and make a few punctures in the walls. Then glue them with tape to the back of the fan and fill it with ice cubes. Simple and effective.
