Kid Craft: grass seed jars

Janis's grandson made these in school and it's such a cute idea I asked if I could share. Super simple, but how fun (and educational) for kids to plant and watch the grass grow. Put some potting soil in a clean empty small jar and add some grass seed (I'm pretty sure this is wheatgrass). Decorate the jar with silly googly eyes (you could add a mouth too with a marker) and a few days later the seed will grow and make "hair". Cute, right?
