Two inelastic devices, a collapse model of a wooden structure and a liquefaction model, are developed for repeatable experiments. This paper contains the outline and use of them. In the wooden model, rubber cords and magnets are installed not only for tying beams and columns, but giving restoring force and stiffness to the structure and keeping configuration of each part. In the liquefaction model, flushing system with a small pump demonstrates simplified liquefaction. Thanks to the portability as well as easy repeatable experiments of collapse and liquefaction arriving to inelastic ranges, these are useful for education of earthquake disaster mitigation.
