Color Changing UV Beads

Color Changing UV Beads


Science Guy Steve Spangler should have known better. Not all sun screen lotions are the same. Instead of using your skin as detector of ultra-violet light (UV), try experimenting with Energy Beads or UV Beads. These indicator beads change color when exposed to UV light. It's an amazing way to test the effectiveness of sun screen or to see if UV light is really blocked out by filters in sun glasses.

Wonderful

My frist grade students were blown away by the color changing beads! We did it as an experiment, I told the kids that something would happen when the beads were exposed to sunlight (which is what we were studying). They learned that "something" in sunlight is different from the light in our classroom. We are moving on to new activities but this was a wonderful science/art project that they could take home and share with their parents!!

This is fantastic or should I say Funtastic and very important for those who have young children, also for car window manufacturers, we know the Sun's ray's have increased in intensity and we also know its not good for our health...this is great and I will be buying some of these beads to carry out my own experiments
