Wow, this WILL blow your mind.  Or prove you’re dead to the world (if your mind isn’t blown).

It’s Mensa Mind Challenge Month! To celebrate the life of the mind, here’s this amazing video.

And here’s Mensa’s 1st challenge: 

Challenge #1: We suggest telling someone else three cool things you’ve learned about the brain. Teaching others not only helps them, it helps solidify facts and abstract thoughts in one’s own mind. Give it a shot!

Hexaflexagons!!

Happy October! Behold this lovely tale of extra paper, folding fun, and the trans-dimensional colortastic geometric wow-fest that is the hexaflexagon!!

Can someone fold me a few of these and send ‘em over? That would be great. I fully endorse not paying attention in math class if you’re gonna do this instead.
