If you’ve been cursed with spending most of the work day in a room without an AC unit, here’s a little something that might improve your situation.

Say goodbye to sweaty palms, no matter how hot summer is. This is a fun little project someone came up with at Instructables, which will provide users with a thermoelectric cooling unit that attaches to their wrist. And, believe it or not, this can rapidly cool your entire body. The unit is meant to be used to cool down after working out, or just because: who doesn’t enjoy being cool in the summer, anyways? As long as you can find some electricity, or are willing to carry a battery around,,,

See the video below these lines to learn more about it, or follow the link to Instructables to see the whole thing.
