You have to get yourself one of these. They are easy, completely maintenance free and fun to look at. My husband got me one for Christmas a couple years back and it was my favorite gift. The ecosphere contains the perfect amount of water, air, and algae to sustain the life of the microorganisms (shrimp) within. They are small enough to put on a desk, dresser or shelf in your work or home. I totally love science and this little gift has brought me tons of entertainment and joy. Get one today!
