The boxes are really easy to make, you just fold them up and then blow into the open end and they turn into a box and you can stuff them full of goodies through the hole you used to blow it up. Origami Instructions - Origami Water Balloon - Origami Water Bomb
Great Idea! One of the things our guys really like, I take a piece of computer paper and fold it into an origami box(water balloon), then I stuff the paper box with treats, paper, sisal, straws, anything I can find and hang it in their cages or place it on the bottom. They love tearing them up and pulling all the goodies out
