The train track optical illusion that's bewildering the internet
This video - of a father shuffling around his son's toy train tracks - has bewildered the internet. Can you figure out what's causing the optical illusion? It was posted on Twitter by BBC trainer Marc Blank-Settle on Wednesday evening, and been shared thousands of times since then. The track on the bottom appears to be much longer than the one on the top, but when one is placed on top of the other, its clear that they are in fact the same size. Many viewers were left completely dumbfounded.
