Our universe hides many mysteries from us, sometimes in plain sight. Humans don’t know everything there is to know about physics, for example, but we’re constantly looking for new ways to quantify, and characterize the many elements that make up the material world.

Even our own eyes deceive us when we least expect them to. There are countless drawings and sketches that have been tailored to show us that our minds can be easily tricked. Check out this elaborate drawing: Do you see a rabbit or a duck? And did you know how much stress you’re under determines how you see this image? Incredible!

Now a dad is showing the internet another neat mind-trick, only by using his toddler’s toy train tracks.

Marc Blank-Settle was playing with his little boy when he placed two train tracks side by side. At first glance, one appears to be longer than the other. But when he places one on top of the other, they’re exactly the same length.

The dad posted a video of this phenomenon on Twitter, and ever since, people have been watching in hopes that the optical illusion wouldn’t work on them.

The optical illusion, called the Jastrow Illusion, was first discovered in 1891, and in this example, happens when the top train track is juxtaposed with the longer side of the bottom track.
