We propose a new device called 'World-Stethoscope', which translates different phenomena into sounds. By using the device with supportive morphs in eToys, our real world can be connected to the computer world. It would provide a new kind of laboratory for children. We also integrate NetMorph with the new system to achieve the collaborative works of the children all over the world.
