Chemistry professor Richard Pashley says he’s found a way to clean clothes without using soap. The key to his discovery is a process called “de-gassing”, which removes air particles from the water. Once de-gassed, the water can apparently remove even the toughest stains, without using an ounce of detergent. Right now, the water can only be de-gassed by freezing it in liquid nitrogen (not exactly practical for soccer moms or college dorm residents), but Pashley plans to develop semipermeable membranes, similiar to those used on oil rigs, that will de-gass water as it passes through.
