    DIY Air Conditioner

    2nd law of termodimanics says nothing to you ? ? Where are you freezing the bottles ? In your refrigerator ? The cold in the bottle "cost" you an identical heat in the rear of your fridge ! So, you are doing nothing than heating your room a little more than cooling it !! The heat of the fridge plus the heat of the motor of the blower are more than the cold you get from the bottle !! Fisics !!
