If you've got a recent-ish smartphone, I would highly recommend getting yourself a Google Cardboard for watching YouTube 360 videos, it really makes it even cooler. Yeah it's "poor man's VR" and certainly not in the same league as things like the Rift/Vive, but it's 15 bucks, so why not? I definitely feel like I've gotten 15 bucks worth of use out of mine, mostly because of videos like this.
