1. Mix 2 cups water, 1/3 cup vodka, into a Ziploc freezer bag and place in the freezer. Because the high alcohol content in the vodka it won’t freeze but rather congeal into a malleable ice cold gel. You can also add food colouring to the mixture if you would like a particular colour.
2. Similar to the first, mix 1 part rubbing alcohol to 2 part water in a Ziploc Freezer Bag (1 quart size). Remove air and seal bag. Place bag seal side down into another ziploc freezer bag, remove air and seal that bag. Place in freezer and use (and reuse) as needed (nice and slushy!).
When taking them from the freezer to use, wrap in towel first before applying to body. If they freeze too hard and aren’t slushy, simply allow them to melt and then add more alcohol.
