Homemade Slushies

So I don't know why I never thought to make my own slurpee or slushie before. My boys are addicted to the sweet treat and I'm often a softy at the grocery store to keep them occupied so I can concentrate...

As a random idea the other day I threw some lemonade and ice into the blender and wa-laa! Instant slushie. It's not quite a slurpee consistency, but still good, my boys were occupied for quite a while at home. I know some of you are thinking, "duh" granadas have been around forever. Yes, I know, but I've never made them. And the virgin version of the drink is definitely frugal... and hits the spot on a hot day.
