Virtual Reality Experience

throughout my virtual reality experience i was amazed! it looked so real. the water fall was personally pretty scary i felt like i was going to fall. and the grand canyon was amazing it was miraculous and I felt that I was actually there it was an amazing experience and an amazing way to show people the different things on line all in a "phone" and it seemed so real! I think it is an amazing invention for who ever invented the virtual reality it was overall superrrr cool it is a memory to remember! a question I have is that who invented the vertual reality and when did they invent it and how did they invent it are my questions
