Truly, there is a Moving Sand Art Picture Rainbow Vision Sand Pictures for everyone (and in many cases, more than one!) Each piece is handcrafted with love and attention to detail. He uses a complex, yet beautiful blend of sand which is carefully selected for each frame color and / or movie image. The soapy water provides the medium for the sand to fall, but the real secret is the air. It is the air barrier that separates the sand from the water. That is it: air, sand and water! The sand will search to find the weakest link in the air-bubble barrier. The flow of sand between the bubbles will create dunes, mountains, and valleys. A slower flow of sand will result in a delicate trickle of sand making more dramatic peaks and valleys. A faster flow of sand will make dune shapes. The Sand Art Pictures are educational for children while soothing and relaxing for adults. There are many sizes and shapes to choose from. There really is something for everyone! A sandpicture will do several times a day what mother earth takes millions of years to accomplish.
