CD Case Planter Stand

My daughter's class is learning about the structure of plants. They are going to do a project where they grow a plant inside a CD jewel case. The jewel case allows them to see the root structure of the plants. While growing they have the jewel case stand on its narrow edge. I thought it might be helpful to have a small stand to keep them from falling over.

The stand just presses onto the bottom of the jewel case. Some jewel cases are thicker than others but I found the tabs will flex to accommodate them.
