Practical Tips: Cutting Onions- No more tears

Jessica told me that if you run water while cutting an onion you won't get teary eyed. I've tried it and it works, but why. Today I was watching the history channel and they explained why it works. Onions contain high levels of sulfur when you cut into an onion sulfer is released into the air and combines with the natural moisture on the surface of your eyes to create sulfuric acid. You tear to dillute this acid further. So in conclusion anything that can capture the sulfur vapor and combine it with water would effectively neutralize the sulfur enough so that it won't form sulfuric acid on the surface of your eye.
