How To Make A Fan Blow Cold Air Without Ice. Have 3 plastic water bottles and put 3 tablespoons of salt into each. Place the bottles 15 cm in front of the fan.
I just use a spray bottle full of water. Use ice for extra cooling. And it might not be very frugal since you have to run the fan most of the night every night.
Position this in front of the fan so the breeze is cooled from the iced.
The fan will blow air coming from the ice or frozen bottles producing cooler air. Have 3 plastic water bottles and put 3 tablespoons of salt into each. Once you believe that the washcloth has been thoroughly soaked you are going to want to drape it over the front of the fan. You may recall that this neat contraption used a bucket of ice water and gravity to make cold water flow through a coil of pipe attached to the back of a fan which made it blow cold air.
