Christmas in July Party Several years ago when my daughters were younger, I had a Christmas in July Birthday party for them since their birthdays are just 2 weeks apart. I made and froze 100 snowballs from a blizzard we had in March of that year - just freeze in plastic supermarket bags - and kept them hidden in my garage freezer. The snowballs stayed the same consistency as when I froze them. I decorated a Christmas tree with sunglasses, shovels and pails and I also made Christmas cookies. I couldn't wait for the big surprise at the party - snowballs in July. Each child had several snowballs (which felt great for a very hot summer day). Of course, they had a snowball fight and we saved some snowballs for them to jump into the pool with. I'm sure it was a party they will never forget.
