Use a cellulose sponge as a DIY ice pack
Whether you’re packing your kids’ school lunches or looking for a lightweight cooling solution for your camping pack, a cellulose sponge can work miracles.
“Wet a clean cellulose sponge and place in a zipper-lock bag. Freeze and take along as an ice pack for summer outings,” suggests Maker. Then, “Use it as a clean-up tool when you’re in a pinch at a picnic!”
