This is a demo of an Oculus Rift virtual reality system that's been synced with a roller coaster to give the rider an entirely different experience. In this case, riding in a flying chariot being pulled by a winged horse. There's also an outerspace experience. Both look intense. So, what do you say -- if you puke while in virtual reality, did it really happen? "Yes." But you don't know that. "Yes, I do." Fine, then you sit behind me on the roller coaster and we'll prove it together.
Keep going for the video, but skip to around 1:50 for the action.
Thanks to SnowMonkey, who learned the hard way why they tell you to keep your arms inside the coaster at all times and now has to have all his bananas peeled for him.
