Ben and Pia dive into the amazing science behind why cutting onions makes our eyes water! Join them as they discover the invisible chemical workers, crying gas, and protective eye knights in this tearfully fun adventure!

Fun Fact: Onions create sulfur compounds as a natural defense mechanism to protect themselves from bugs and animals - but we humans are brave enough to eat them anyway!

Did you know? You can put an onion in the refrigerator before cutting it to reduce the tears because cold slows down those sneaky chemical reactions!

What makes YOUR eyes water? Tell us in the comments below! We love hearing from our brilliant little scientists!
