16 Christmas Gifts For The Science Nerd In Your Life

8. Marimo Ball EcoSphere

These teeny tiny spheres are the perfect way to bring a little greenery to your surroundings, without the hassle of actually having to look after anything. These sweet little green blobs are actually tiny balls of algae originating from Lake Akan in Japan. They require very little care, but they do enjoy being tickled every now and again to keep them green and healthy (no, really, it's adorable). Once your Marimo is established, you can even propagate new baby Marimo by splitting them in half and moving to a new sphere. Get your little green pets here.
