The Illusion Only Some People Can See

i am going to turn myself into an optical illusion by going through this window right here okay not good i was gonna say i'm good i'm not good okay so you're looking at this window and it looks like it's turning around except here it stops now i keep rotating but the window is rotating through me what is happening this video is sponsored by nordvpn they help you create the illusion that you could be anywhere in the world let me back up for a second this is the first part of a three-part illusion what do you see well there's a window and it's turning except it stops and reverses direction so the window is oscillating back and forth that's what most people see when they look at this illusion except that's not what the window's actually doing it's on this turntable and it is rotating continuously this is known as the ames window illusion and i saw it on an old australian tv program called the curiosity show and i was curious so in this video i'm going to dig deeper into this illusion than anyone has before you know the window itself is not a rectangle but a trapezoid you can see this side here is much shorter than this side over here and that is essential to the illusion also essential it is shaded to make it look 3d but it's actually just a two-dimensional card with the same image on both sides so now that you know exactly what this object looks like and what it's doing can you correctly perceive the rotation rather than the oscillation i still can't it still looks to my brain like this window is going back and forth okay here's an idea i'm going to attach this rubik's cube to the short side of the trapezoid so we can keep track of it as it goes around are you ready okay okay the rubik's cube is going around everything seems normal but now what is that it looks like the rubik's cube is continuing to go around but the window is oscillating back and forth there goes the rubik's cube around the back i don't even know what's happening whoa look at that it looks like the rubik's cube is out drifting by itself out in front of the whole illusion what is happening okay new plan ...
