Were they punching each other with the snow?
There was either rocks inside, or they used the heat of their hands to compact and harden the snowballs.
Probably the latter, but possibly both techniques were used.
My brother and I used to put ice in ours. Better than throwing rocks since you can claim ignorance.
Or take the hand hardened snow, roll it in powder, and claim ignorance.
I know, there’s lots of variations on how make a snowball maim or cause blunt force trauma, but adding rocks and making ice balls in your hands seemed like a consise way to explain why those kids all look like boxers who lost a 10 round slug fest.
Well it’s not a snow ball social, Nancy!
