Sky Jello: The original recipe is now closed (boo passwords) but here is someone who relisted it. Basically: packages of Berry Blue Jello * 2 cups of whipping cream * 1/4 cup sugar * 2 cups of ice * parfait glasses or any clear containers that you can see through - the key here is to use the ice to quickly set up your jello and you're using ice instead of water. Got that? Cuz I screwed this up the first time I made it.
