PROBLEM TO BE SOLVED : To provide a tool floating in the air without requiring a body for enclosing a rare gas or the like. SOLUTION : A lightweight covering material 1 is made not to be crashed due to an ambient pressure, using a firm and lightweight support 2. By depressurizing the space inside the material 1, this tool can float in the air because the support and the covering material are lightweight. COPYRIGHT : (C)2007, JPO&INPIT
