University of Oklahoma physics professor Kieran Mullen showed how NOT to recycle a laptop when he drove home his strict no-gadgets-in-class policy with the help of a bucket of frozen nitrogen. He arranged for a student to bring in a dummy laptop which was then confiscated and dunked in the hyper-cold liquid nitrogen. OU freshman Lindsey Brinkworth told the Oklahoma Daily, “He said: ‘This is just liquid nitrogen, so it alone won’t hurt the computer — but this will. Then he threw it to the ground and told him to have IT fix it.”
