In this video I show off my Brain Cube in an Impossible Jar! I’ve been wanting to make an impossible jar with a Rubik’s Cube forever! I got the jar from my brother who got it as a Christmas present.
Using my Google-fu I found where you can buy the jar head: http://bit.ly/GlassJarHead
I got the Brain Cube from Marbles the Brain Store here: http://bit.ly/BrainCube3x3
