The Penrose Rectangle is what’s known as an impossible object, an optical illusion that is drawn to look like a three-dimensional thing that could never actually exist. If it’s hard to see at first, cover one half, then the other, and then look at it again: it’s a geometrically impossible shape.
Jonathan Harris draws objects in YouTube videos (including possible ones), but he has a series of impossible objects that are fascinating to watch and learn, including the Penrose Triangle, an Impossible Oval, and the Penrose Staircase.
We love these impossible forms, as proven by our logo. And if you draw any impossible objects, tweet us a photo of it. We’d love to see.
There are more optical illusion videos in the archives, including the not-to-be-missed work of Kokichi Sugihara, who builds impossible drawings in three dimensions.

DIY experiments and videos are two of our favorite things, so we were thrilled to hear about GE’s Six Second Science Fair. The week-long celebration resulted in over 600 submitted projects, and GE’s compilation video, via jtotheizzoe, includes a wide variety of shared experiments from kids and adults alike.
It’s fun to watch, but it’s also an excellent resource for checking out science experiments (like these) that you can do yourself. We’re definitely inspired to try a few…
