My oldest son made terrariums for our science fair. We love terrariums- just google that word and be inspired! Terrariums are containers for plants or animals, but have really gone to a new level with the creativity people use when selecting containers and plants. A terrarium can be completely enclosed (like our above jar), or open at the top (like the light bulb shown below).
this tutorial for getting the top off of a light bulb. Then used a funnel to get the layers of pebbles and dirt inside. A long skewer helped us plant the tiny plant inside. These plants have thrived with only a few sprinkles of water at the start.
