Set your young chemist up for an afternoon of science-fueled magic with a deceptively simple activity starring baking soda and vinegar!

In this Halloween-themed activity, young learners will find out what happens when they mix two household items together to create a surprising chemical reaction.

Get your hands on a concoction that breaks the rules about what's a solid and what's a liquid.

The next time you've got a restless second grade earth scientist on your hands, use this experiment to demonstrate crystals and make a tasty treat, too!
