It is a heavy glass vase I got from Old Time Pottery I inverted on some concrete blocks so they could swim in from the bottom. You have to get wet to submerge the vase and turn it up under water so the vacuum created keeps the water inside. Make sure you have a heavy glass container or the weight of the water will shatter it. (court. of Rick Brown's fb page - Riverview Flower Farm Growing Florida Friendly Plants)
Mix grass seed in with potting soil. Fill up a nylon. Tie into segments with string to make a 'caterpillar." Soak in water till saturated. Then let the kids spray it with water every day after and watch it grow. When the grass gets "too long" let the kids give it a "haircut."
