This Dad's Video Of Shape-Shifting Train Tracks Is Seriously Weird

This is trippy.

Posted on

Marc Blank-Settle, a trainer with BBC Academy, posted a video of himself playing with his son's toy train tracks. He said he was playing when he noticed something trippy.

My toddler's train track is freaking me out right now. What is going on here?!


Needless to say, people were sufficiently freaked out.

@MarcSettle @ohchrisburton that is going to give me nightmares. I do not like it.

And some people had some out-of-this-world explanations.

"I don't like things that I can't explain....bloody trickery!" one woman wrote.

@Crannogphoto @MarcSettle I don`t like things that I can`t explain....bloody trickery!


But it turns out that the freaky illusion has an easy explanation. As some people pointed out, the phenomenon is called the "Jastrow illusion."

@MarcSettle Good ol' Jastrow Illusion. :) You didn't line up the same corners below each other so the lower one's further to the right.

"The fact that the shorter side of one figure is next to the longer side of the other somehow tricks the brain into perceiving one shape as longer and the other as shorter, although it is unclear exactly why this is so," according to the encyclopedia.
