The Sponge Blossoms are the perfect cleaning sponge. In nature, if you want things to grow, it takes water. Even the tallest redwood tree needed water to grow to its enormous size. Which is kind of how our Sponge Blossoms work. They're easy to have hanging around because they're so darn small and handy. But when you need a sponge, just add water and stand back. Instantly, you've got a full-size sponge. It's like nature on fast forward.
