You might ask Paul Quinn if he'll lend you his special popcorn machine to make better popcorn.
Quinn was a graduate student at Lehigh University in 1999 when his adviser, Daniel Hong, started thinking about how to apply physics to everyday things.
...
Hong died of complications from a liver transplant in 2002 and Both moved on to Stanford University, but Quinn, who had already left Lehigh, decided to finish the experiment.
So he built a vacuum popper.
Quinn, now an assistant professor of physics at Kutztown University of Pennsylvania, hooked a vacuum pump into a stovetop pressure cooker, hoping that the decrease in pressure would allow the kernels to expand further than they do in a microwave or in a regular stovetop popper.
To his surprise, the popcorn was almost twice as big as regular popcorn, and had fewer unpopped kernels.He doubled the popcorn's volume.
"The theory is very simple, which is why we didn't think it was going to work," Quinn said.
Although his training is in physics and granular materials, Quinn is continuing work on his special popper, and has applied for a patent on the device.The new apparatus would let the everyday popcorn lover take advantage of the process he discovered, though he's secretive about it for now.
Discover magazine describes it as a contraption with two dog-food bowls and an off-the-shelf microwave.Quinn said results of his testing thus far are promising.
But both Quinn and Chandrasekaran say their work is not just for popcorn eaters.The Carbohydrate Center conducts all sorts of research about starches like popcorn; finding a way to slow the digestion of starches, for instance, might help reduce obesity, Chandrasekaran said.
Quinn doesn't want to have much to do with the food production; he says he just likes the pure physics of popcorn.If he makes money from his new device, then all the better, but he's not expecting much.
"Me, I just like it as a learning tool," he said.
