    Fun Activity for Halloween

    We all know that there's a bit of magic when you can combine dry ice and chemical reactions, right? This combination alone makes for the perfect stem projects for Halloween fun.

    Once the kids know how to make it, they're going to be lining up to make their own fun Halloween science experiment too. 

    Pair the excitement of this with a belly full of Halloween candy and you're certain to have kids bouncing off the wall all night long!

    One of the best parts of Halloween is trying to find ways to paint pumpkins or carve jack o lanterns all while trying to be a bit spooky at the same time. I even think back to my childhood where it was all about glow-in-the-dark fun! 

    No matter what, your child is certain to love trying out this fun Halloween experiment. It's a bit messy, a bit wild, and a lot perfect for having a truly scary good time. 

    Let the kids take turns with this simple Halloween activity. See just how much magic they can make as well. They'll love being able to use their minds and hands for this fun STEM activity.
