Discover This: Optical Illusions

I get a kick out of the rock band OK Go. When they first started out, their quirky DIY music videos made me smile because they captured people’s attention without spending a fortune on flashy production costs.

With their success, the band’s music videos have gone a bit over the top. Check this one out, which is full of optical illusions.

Wild, right?

Optical illusions are fascinating tricks our brains play on us. In an effort to quickly make sense of the vast amount of sensory information we’re bombarded with all the time, our brains rely on quick “rules” to sort out what we see and hear. Watch this 5-minute TED-Ed video that explains what exactly happens to our minds. You can even take a review quiz afterwards to see if you got everything they try to explain.
