When I was a kid, winter always seemed to bring at least one big snowfall every year. It’s possible these snowfalls seemed larger in comparison to the ones I see now simply because I was about two feet shorter back then, but whatever the reason, I remember engaging in numerous snowball fights over the years. As the fourth in a family of 12, and growing up in a neighborhood filled with children, I never lacked for fellow snowball fight competitors. So, I watched and learned a few tricks about packing snow to create the best snowballs and snow forts. What I didn’t know was that all this involved physics.
