Spray-Can Cooling Foams Keep Japan Comfortably Chilled in This Summer Heat

How to Stay Cool in Japan
via Japan Trends

It seems like the Japanese always have the coolest technology--in this case quite literally. The hip new way to stay cool in an increasingly energy-conscious Japan: cooling foam or gel spray-cans that go right on the skin and provide an instant cool down.

These cooling sprays apparently aren't brand new, but a thing isn't a "thing" until it goes mainstream in Japan, and this summer that's what's happening. City-dwellers are using the products to cool down on the subways or on the streets. Particularly cool: the foam-like spray that hardens quickly out of the can, so users can make cooling wristbands or neckbands to help keep their core temps under control.
