I use these color-changing solar beads in my environmental systems class for a solar radiation lab, and they have proven to be a fantastic teaching tool. The variety of colors they exhibit is not only visually captivating but also helps illustrate complex concepts effectively. My students have found them engaging and informative as they respond to different levels of solar radiation. The great range of colors makes it easier for students to grasp the nuances of solar energy, and it adds a fun, interactive element to our lessons.

These beads are a great value for the quantity, versatility, unique style of color changing based on sun/cloud and darkness will give a glow and is why I ordered these beads. They are a good price as well and I plan to use for braid styles in my daughter's hair and bracelet making.

Every year I use this for my classroom. The kids absolutely love it. Instead of using the thread/yarn that it comes with, I have my second graders use pipe cleaners. Pipe cleaners hold the beads in place so I don't have to worry about beads all over the floor. Plus, they can just twist the ends. The best part is watching their reactions when they go outside and squeal at the sight of the beads changing colors. Yup, every year and it doesn't get old.

These beads come plentiful and work as shown. They consistently glow brightly and last a long time in the dark. The color changes before your eyes with UV exposure. They were 100% what I wanted. The only issue is that they come in a big bag mixed up by color. So you do have to sort and pick th from that, but with consideration of how wonderful they are it’s worth it

These beads are awesome. Perfect for day festivals or raves that lead into the night. However it comes in a giant bag all mixed up. I thankfully had a uv flashlight but i took 2.5 hours just to sort them. Still it is a great recommendation for someone who wants unique beads.
