A little girl named Elise performed an age-old science experiment: submerging a sweet potato in water to see how long it took to sprout.
The results weren't what she expected. The conventionally grown sweet potato languished, the one from the organic grocery store sprouted a little and the one from the organic-only store went bonkers.
Elise learned from a produce-department employee that the conventional sweet potato had been treated with a chemical called Bud Nip, also known by the chemical name chlorpropham. It's an herbicide applied to tubers so they can be stored longer without sprouting. The U.S. Environmental Protection Agency classifies chlorpropham as "slightly toxic," meaning it can cause mild skin and eye irritation.
Judging from her findings, Elise doesn't quite see eye to eye (that's a pun!) with the EPA. She presents her case in a YouTube video embedded after the jump.
