Kodo Coconut is simply a brick of compressed coconut husk. Originally intended as a planting medium, this hard brick slowly expands to four times its size in water. Spongy and fibrous, the resulting material has a unique feel and interesting texture. When dried out, the light husk particles are fun to dig in and pour. Once the kids are finished, they can toss it in the grass or garden, or better yet, plant seeds and start a whole new project.

Should coconut be avoided by someone with a tree nut allergy?
