Earth's coldest temperature is minus 129 degrees Fahrenheit in Antarctica. Brrrrrr! But that's nothin' compared to what could be the coldest room in the world: at Bellevue's Northwest Cryotherapy Institute.After just three minutes in this room, ice forms on your skin. Even Lebron James uses cryotherapy for a speedy recovery. Plus, if you go, you just might meet Jeremy Taiwo. The Olympic decathlete from UW works at the Institute. Freeze on!
