Some of my kids don't even remember ever seeing actual snow, so this was kinda fun. The only trouble was that the snowballs were no longer light and fluffy. They were hard, compact, ice bombs! After instructing the kids not to throw them at each other or the house, they set about trying to destroy the snowballs.
The preferred method of destruction was to slam them into the asphalt in the hopes that the ball would shatter into smithereens. (You can see white specks on the pavement in the following photo that prove they succeeded.)
We put the few remaining snowballs into the cooler on the way home to help regulate the temperature. Unfortunately, they melted and leaked out a hole in the bag and ruined our favorite travel treat! Rats! Oh well, it was still fun and educational. :)
