Summer is hellish hot. And when your whole country is trying to conserve energy, as they are doing in Japan, people need to find alternatives to turning up the AC. The Cool Foam is one of these new solutions.
Packaged in 220 ml. aerosol cans similar to silly strings (or the Turbo Tango), the foam hardens a bit once exposed to air. In that form, it can be molded into any shape you want, including wearable ones like necklaces, wristbands and full-body armors (we’re not sure if a single can will suffice for the latter, though).
