I was thrilled when I found this method for making your own homemade ice pack. I’ve tried freezing water bottle or juice boxes but they are never thawed by the time my kids eat lunch so then they don’t have a drink. This DIY ice pack method is so simple and when they get lost, it won’t cost a fortune to buy new ones.
How to Make Ice Pack for Lunch Box
- Purchase an inexpensive pack of sponges – These sponges will not be cleaning a thing so just find a big sponge that is cheap. One of the best aspects of using this method is that when your child accidentally throws it away, it is no big deal.
- Soak the sponges in water – Just grab a big bowl and let the sponges completely soak up as much water as they possibly can. It is the frozen water in the sponges that provide the cold.
- Put each sponge in a small zip style bag – These bags serve two purposes. First and most obvious is that as the ice melts, it contains the water so it doesn’t make a mess. Secondly, keeping that water contained allows the melted sponge to reabsorb the water so it is ready to refreeze.
- Freeze the wet and bagged sponges overnight – In the morning, all you need to do is toss that lunch box ice pack into their lunch. Once your munchkin gets home from school, they just toss the bag back into the freezer so it is ready again in the morning. After a few weeks, you might need to add a bit more water to the sponge before freezing as a bit of evaporation does take place over time.

I would probably wash them (hot water/bleach) after the 3rd use. Since they only cost a dollar at the dollar store, maybe I would just toss after the 3rd use and then buy new ones.
Great tips.
