Willy the Worm - Color-Changing Houseplant Water Sensor

This cool new Willy the Worm Water Sensor is a whimsical color-changing terracotta worm that pokes up from the soil of your favorite houseplant to let you know when it needs watering. The worm changes color with the moisture level of the plant's soil. So if it's a lighter shade, the plant needs watering, and if it's a darker shade, the plant is just fine. It's also kind of cute and funny looking, so you might actually notice it just long enough to spark a reminder to actually water that thirsty, sad, and depressed drooping houseplants for once.
