Even though we don't have kids, we use a lot of ice packs. If my husband has to travel, he likes to pack an insulated bag with drinks and snacks, and I get migraines quite often and ice packs help a lot. Another fun thing if you have it on hand, is that you can use food coloring and make it any color you want. If you do have kids that use ice packs, you could let them choose what color they want theirs to be. Then there's no fighting over who gets to use the baseball one!
For my pack in the pic above, I doubled the recipe to have a bigger one. With the recipe doubled there is more mass (or volume if want to get technical) and so feels a little more solid when your first take it out of the freezer.
1 1/2 C water
1/2 C rubbing alcohol
zip top freezer bag - quart size for regular, gallon size for double
a few drops of food coloring - optional
be sure to seal the bag well, and place in the freezer. It's best if it can lay flat. The rubbing alcohol keeps the water from freezing completely so it's more like a really stiff slush which is great when you want to wrap around your knee of a can of pop.
Until Next TIme.....
