This week's GizWiz Gadget is the Personal Cooling and Heating System. Keep yourself cool under the heat of the summer sun with the Cooling Bottle and warm under the cold of the winter. Designed for portability, this hand-held device fits in most cup holders and runs on battery power. The fan draws in air, circulates it around the Ice and sends cool air out. Whether you use it at an outdoor sporting event, the beach or just in the comfort of your own home, this device is indispensable when the weather heats up!
