Corn in The Cooler

Scott DeSimon, writer at http://www.bonappetit.com/ stumbled across a quick and fun way to make a large quantity of corn on the cob. Get a large cooler, throw in the corn and add a couple quarts of boiling water... that's it. 30 minutes later the corn was cooked perfectly and ready to eat. I can't be the only one that has never hear of this. Have any of you tried this? Any other easy kitchen hacks you think a lot of people don't know about?
