Mini Lazer Discette Holographi

A metal disc coated with a specially designed Diffraction foil. Spin the disc on a smooth flat surface and enjoy the amazing color patterns. It is like watching a kaleidoscope! The Rainbow Colors created by the Lazer Discette are the result of the parallel grooves etched onto the surface material. While this process has been used since the 1700s, Lasers now allow us to etch 14,000 grooves per inch! The Kaleidoscopic array of colors and patterns is a result of light striking these grooves at constantly changing angles, breaking the light into various bands of color! Approx 3 inches in diameter.
