Blue Glow Stones: Add a little nighttime magic to your yard. They soak up the sun and at twilight, release it to create a stunning lighting effect along a walk, around a tree, or to highlight other landscape features
DIY - Glow in the dark pots with mums for fall/Halloween. Buy a flower pot that you really like and use Rustoleum's Glow-in-the-dark paint to paint the pot. During the day, the paint will absorb the sunlight and at night the pots will glow.
