Air-Conditioning in a Can

In Japan they have cooling foam, a menthol-based substance that can be styled into bracelets, necklaces, and large blue clumps. These bracelets and clumps apparently feel like “giant ball[s] of confetti” and are filled with air bubbles that, when squeezed, “expand and then pop, releasing a refreshing breeze of cool air.” You are not supposed to eat the cooling foam, handle the cooling foam if you are pregnant, or spray the cooling foam directly into your eyeballs. “Someone is going to try to masturbate with this,” notes YouTube user asta49.
