Retroreflective Glass Beads

PRODUCT TYPE: Demonstration

These microbeads are retroreflective beads—tiny glass spheres designed to effectively reflect light back to the light source. They are commonly applied to wet paint to create reflective surfaces and markings. They work by allowing light to pass into one side of the sphere, reflect off the opposite side, and return to the source in the color of the paint used. The type of glass used is important for achieving a specific refraction index, the angle that light bends when entering and leaving the glass.

This tube contains 40mL of type III glass beads, the highest grade of retroreflective beads which are designed specifically for marking airport runways and taxiways. Use a salt shaker to apply a coating of beads to a freshly painted object to create an airport-grade retroreflective surface.

The reflective beads in the glass tube jar are well-packed in self-sticking bubble wrap and paper in a little box. Their reflective nature is like tiny water droplets on a car window on a sunny day, but with more oomph, like a magnifying glass. Sticking your finger in them, they don't stick to your finger. The glass tube jar is filled to the brim, so it's a generous amount. The length of the tube jar is just over 4 finger's width, holding it in my hand. Not a bad amount. I would say if you want to do a large art project, get two, just in case. My mom is going to love this. Considering on getting one for myself, too! It'll probably look pretty inside a clear ball Christmas ornament (like those decorate-yourself ones from a dollar store or craft store).
Thank you!
