Japanese researchers have developed a spray-can cooling foam that supposedly feels like an ice pack. That’s not all, there’s also a fizz spray which cools the surface of your skin to -9C. Video after the break.
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.
