"A few years ago I got tired of laptop fans that slide around, and didn't cool very well. This was my husband's solution. $10.00 clip fan, red duct tape, and an old foam wedge laptop desk. Best fan I have ever used."

"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!"
