inventing a solution to a perceived need

when i went to college, i was working full time as a nuclear shift test engineer, and raising a family. no violins please. that was just the way it was. so i had damned little free time to invent things. not so the case of the students that put this ingenious machine together.
college.... where fresh minds get dulled with alcohol. i think i'm jealous

i'm guessing they are engineering students. a liberal arts major would have just put the fridge next to the couch within easy leaning distance.
