Making a Homemade Ice Pack

I really like the slushy ice packs you can make with this. Details within the link. Lots of recipes online. Just make sure that you in some way delineate the fact that this bag contains alcohol, and if you have children in the house, preferably use cheap vodka rather than rubbing alcohol, which is toxic if ingested.
