MIT's wonder - walls made of water, people still walk out dry
Massachusetts Institute of Technology architects have developed a 5,400-square-foot building that has walls made of water. This building will be displayed during next year's world expo that will be held in Zaragoza, Spain.

People visiting the expo will encounter walls made of water. They will also be encouraged to walk to through the water walls. The developers of this amazing technology have stated that it can be compared to an ink jet printer where software controls the flow of ink droplets.
Similar to the inkjet printer this structure also uses software that enables the valves to be opened and closed at precise locations, which further creates gaps in between the walls. These gaps can be used as doors. When a person moves towards a water wall, sensors detect the person and stop the valves at the precise location from where the person is expected to move.
The best feature of the whole design is that the walls can also be used as a display screen. The 5,400-square-foot structure can also be made to vanish in seconds. The roof of the whole structure is movable and can be lowered from the 16-foot standard height to ground in seconds.
