Diffraction Grating Glasses

Fantastic Give-Away for guests to our Drvie-Through Light Show!

These glasses were a huge hit as we gave them to our guest as a FREE gift!

Great for Halloween instead of candy

These are a favorite for the kids on Halloween. In the office they are a mile maker. For my patients it also brings a smile when they can’t get out side. I also use these for Holidays with neighbors and the glasses always bring a smile. They remind us to be a kid again. :))
