Interactive simulations can help explain how things work. Explain3D simulations are built in a 3D environment where the user can rotate and play with them. The main advantage is interactivity—providing educational simulations on technical mechanics, such as engines, jackhammers, submarines and hydroelectric dams. Processes that are difficult to imagine are explained in a fun way. The simulations are online at explain3d.com, and access to the system is free for all users.
There are no technical requirements. It is currently available for Windows and Mac OS X.
