Did you use one of these awesome weather websites to confirm the triple-digit heat index this summer? If you plan on being out and about in the heat but wish you had a cheap alternative to store-bought freezer packs, then be sure to check out this great DIY project. Not only is this the most affordable ice pack you can get, but in case of minor injuries (especially for kids), these make a great cold compress.
Bonus tip: If you like the idea of having a blue pack, similar to the ones you would buy in grocery stores, add dish soap to the ingredients. This can also be a good way to get creative.
Another good option not covered above calls for using corn syrup. While this ingredient is a good alternative, especially if you want your ice pack to be more flexible, you run the risk of having a really sticky mess if an unfortunate spill occurs.
