how to cool a room with a simple method!
By screwing plastic bottles to a piece of cardboard and hanging it in the window will make the air flow differently!!! Amazing way to cool a room by recycling plastic bottles!!!
When air velocity increases, pressure and temperature both drop.
Take a piece of sturdy cardboard and a lot of recycled plastic bottles. The bottoms and necks of the bottles are cut away and then stuck into a series of holes cut into the board.
when the finished cardboard is put into a window or door a cooling effect in the room is noticed immediately!
