For this episode of Nightly News: Kids Edition, we celebrate “Bring Your Kids to Work Day” with kids joining us in the audience for the first time ever! We answer their questions, which some of you might also have at home. Dave Price explains the science behind thunder and lightning with the help of some junior meteorologists. Then, our friend Jimmy Fallon tells us about the joy of making people laugh. If you’re thinking of getting a puppy, our expert weighs in on everything you need to know about puppies! Plus, "vomiting" watermelons?! We have a fun experiment with Kate the Chemist and her mission to make science fun! But, please, don’t try this at home.
