Here is a simple but useful idea for cooling if you do not have air conditioning. Place a bag of ice inside a metal bucket as shown. Cover the bucket with a small towel to cover just the top of the bucket. Place a fan behind the bucket and turn it on high. The bucket will begin to get cold and give off cooling air to the room.
This maybe a redneck air conditioning idea but it does help. Change out the ice once it has melted to keep the cooling going.
