AbstractFor promoting the wide use of inexpensive zero-g facilities, a new device is developed based on the yoyo principle. The yoyo motion of a capsule enables to produce its successive rise and drop motion that create the reduced g environment inside the capsule. For the first step of its development, an indoor sized model was manufactured for the educational purposes. Its reduced g ranges the lunar and planetary surface g levels, worthy of its name Ez-Space. Further improvements are promising on its operational characteristics, such as the larger in its physical size of experiment volume and the higher g quality approaching to zero-g.
