HOUSTON – Known for their mommy and me science experiments on their YouTube channel, ‘Mommy and Me: The Listers,’ Crystal Lister and her four-year-old daughter are back with easy Halloween-themed experiments you can test with your kids at home.
* Before starting any experiment, The Listers have a Science Safety Announcement: Make sure you’re conducting science with your grown-up!
1. Spooky Science Handprint

How to experiment:
- Mix equal parts baking soda and water in the shallow dish to make a solution.
