This may sound silly but a long time ago i see a lady on a old cooking show use matches! She took 2 matches and put them in each corner of her mouth (not lit) when cutting the onions. It works try it!!

 I agree with the matches not lit but what i would suggest is a tea spoon it'll do the same sort of puts a funny smile on ya face but it does work honest

 I've heard that if you cut the root end first, it's less. I've also heard that if you run the cold faucet it won't cause the tears.

 I love onions too, but cutting them has always made my eyes tear and burn. There is a way to eliminate this. Cut an onion that has been soaked in cold water for about 20 minutes. Then use a very sharp knife to prevent too much onion juice from leaking out permeating the air. Onions release an enzyme called aliases, which later convert to sulfinic acid. These sulfinic acids are very unstable once they hit the air. This is what causes tearing and eye pain. But a cold onion cut with a super sharp knife in a well ventilated room can eliminate the tears. This is the best remedy I've found for stopping tears from the coveted and delicious sliced onion.

 Yes, after peeling off the outer skin of the onion dip them into water for sometime and then cut onions by taking directly from the water, you will not have tears from your eyes.

Happy Cooking.

 Employ a kitchen helper and delegate such chores. But remember to have true empathy from across the kitchen!

 Try cutting the onion with the top up rather than across the center while running it under water. It works for me.

 Using a chopper or food processor works wonders. If not, I rinse the onion under cold water while cutting.

 Here's a foolproof idea, put your whole onion in the freezer for 15 minutes before cutting. Guess what, no tears! Try it.

 Alton Brown said cut the onion by the stove with a burner lit, it helps eat the obnoxious 'fumes' up. Also use the sharpest knife you have to help stop some of the 'fumes' from escaping. Cleaner cuts less damage to the cells.

 I've heard that if you cut onions while chewing fresh gums your tears will stop. I have never tried it but good luck!

 Rather than worry about all of that, why don't you just buy the onions already chopped and bagged in the produce section of the market? They don't cost very much and if you are planning on chopping lots of onions, this would be the best bet.
