Christmas STEM: Snowball Launcher

We built our own snowball launcher! All of my kids went wild over this Christmas-themed STEM activity. It kind of just accidentally came together, but everyone in my house was sure glad it did. 

Your family may want to experiment with other ways to put one of these together – you may have a different collection of supplies on hand that would work well – maybe even better than ours – but in the post, I’m going to share how we made ours.
