Rainbow Vision Sand Picture By Klaus Bosch -- Small size "Aurora Borealis" This is the same sand art that was seen in the Louis Vuitton store windows around the world in Fall 2017. Our sand art comes with an injector to adjust the air and an owners manual. Mesmerizingly different with each turn. A sandpicture will do several times a day what Mother Earth takes millions of years to accomplish. Klaus Boschs KB Collection (formerly Rainbow Vision Sand Pictures) are interactive, ever-changing, mesmerizing and versatile art pieces. KB Collection Sand Art is made in Lustenau, Austria by Klaus Bosch, Sandman. Great educational gift. Check out the Pitkin Stearns website to see the 30+ Scientific Principles!
