So Cool is a personal cooling fan powered by a water-activated battery. Simply insert the base of the So Cool cooling fan into any PET bottle filled with cold water and the water-activated battery will switch the fan motor on to immediately provide the user with a cool breeze. Users can also gently press the spray button to create a refreshing mist of water that serves to cool down them and their immediate environment even further.
