DIY: Styrofoam Terrarium Rock

A terrarium is a closed living space that fosters the growth of plants, animals or both. If the environment of your terrarium is looking a little barren, however, you can add homemade stylized rocks. Styrofoam rocks will add a unique element to your ecosystem and are safe for the plants and animals inside. Even those inexperienced with building rocks can complete the project in under 30 minutes.
