Make An Ice Pack With Sponge And Snack Bag
An easy way to keep your lunch cool is by wetting a sponge and freezing it. Then, take the frozen sponges and put them inside a snack bag wrapped in duct tape for insulation. By doing this, you’re guaranteed to have a cool lunch!
The sponge traps all of the moisture as it melts. You won’t have to worry about any leftovers ending up in your child’s lunch because they are trapped inside. There is no need for a different bag. Simply fill an empty box with dry snacks, and you’ll be set.
