Super Tube - Energy Beads
This is a fun and creative way to help demonstrate the effects of UV (ultraviolet light) that comes from the sun. When the uv beads are exposed to light outside, even on cloudy days, they change from white to colors. When you bring them inside, they turn to white. Regular light bulbs do not effect them because they lack UV light.If you put sunscreen on a bead, you can visibly see the "UV blocking" effects. Experiment with what materials block UV. Includes information and ideas about more experiments. Maybe your son or daughter will invent a new sunscreen! - Makes a great solar educational and "crafty" gift!
