This week Reactions takes science into the kitchen. We're looking at the chemistry behind why onion chopping makes you cry. We get to the bottom of this teary phenomenon and reveal exactly what chemical mechanisms trigger it. The video also features a few chemistry-backed tips you can try at home to stop the tears before they start.
