"The children spent two weeks building the model and were intimately familiar with the layout of the site and buildings as the appeared on the PC monitor," MissionV founder and CEO James Corbett explained. "But the full realization of the scale and perspective of what they built only dawned on them when they were immersed in this reality." Having a virtual presence in the model actually changed how the children learned about it -- and the promise of being able to play in the world they built was bound to be a heck of a motivator, too. It's still too early to say if VR will become a common tool in education, but it's still a blast to watch these kids romp around in a world of their own making. Check it out in the video below.
