Abstract: It is important for not only practical problems but also science education to simulate avalanche motion in a reduced scale experiment. We are developing toys for science education (named Nadaranger 1, 2, 3; Nadare is a Japanese which means avalanche) showing avalanche motion. These simulators are made of transparent plastic water tank filled with fluid and granular materials. By changing the granular materials several kinds of avalanches can be simulated. Nadaranger 1 is a standard type avalanche simulator whose slope length is 15Ocm, and Nadaranger 2 is a desk top type simulator 30cm in length, and Nadaranger 3 is a key holder type simulator 7cm in length whose nick name is Nadaretchi. In these simulators the similarity on head- tail structure is essential to show them real.
