UV Sensitive Beads

at 5:23 am. Filed under Reviews, Toy Hacks


UV Sensitive Beads are fun to play around with, it is interesting to see that there is no UV light present in indoor light and there it lots available in natural sun light. There are so many possibilities, bracelets, secret words with letters made of different colored beads, kids guessing games, etc. On the label it shows pictures of blue, orange, yellow, pink and purple beads. But the bag of beads didn’t contain blue and orange beads so don’t expect to get a variety of all colors. Thanks to Edmund Scientific for providing the beads.

“Solar Beads contain photochromatic dyes that react to UV light and cause the normally white beads to change into vibrant colors when exposed to the sun or UV emitting black light. Then, when removed from sunlight, the beads revert back to white.”

    wow, thats pretty spiffy. It kind of reminds me of the whole glow in the dark beads and products that absorb light then and then glow in the dark.

    Great stuff, love the video. I found a bikini that uses these beads about a year ago. The premise is that the color change will warn you of too much UV exposure in lieu of simply using a time based method.

    You can test sunscreen lotions with those. Apply em to these and calculate the various time it takes for diff beads to change etc..
    Where does one find these types of things?

    That would be interesting to add to a paint color, not sure if it is possible to do but this stuff may work for that application:
