"We received a shipment the other day with dry ice packed to keep it frozen. We did the same USB fan trick that was sent in by Acidcow, but amped it up a notch. We cut a hole in the side of the cooler, and aligned the dry ice packs to allow maximum airflow around them, then propped the lid open so that air is drawn in from the top by the fan, cooled by the dry ice, and blown on the computer user forthwith."
Consider me henceforth impressed!
"We tried again, but with liquid nitrogen. My coworkers halve already threatened me if I go near their liquid argon supply. This is what happens when scientists get toys to play with. Inside the cooler is a plastic jar with liquid nitrogen up to a mid-point in the jar. The fan blows down into the jar, and the cool air comes off the side out of the second fan."
"Hey man, the cooler's broken again. What should we do?"
"... Go get some science, we'll use that!"
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?
