It’s bloody hot and guess what, its going to get even hotter. The very thought to rubbing shoulders with other sweaty co-passengers in the sub is quite a frightening thought. Amidst all this heat and sweat, there is a Japanese savior called the Portable AC Spray. Sprays of cool air promise to bring down your temperature. All you need to do is spray it on to your clothes for that cooling effect. But be warned; don’t spray it more than once in the same area lest you get frostbite!
The portable air-conditioning spray uses flammable ethanol and other products that brings down your clothing temperature to feel like they’re minus forty degrees Celsius. A can of cold air will set you back by $5 only.
