Kenneth Brandon is a Rubik’s cube master. He has recently proven his skills by solving this 17x17x17 inch cube in 7.5 hours. The feat can be viewed in the time-lapse video below, but if you want REAL proof, he has uploaded the entire 7.5 hour real-time video here.
I could not imagine having the concentration that Brandon had for 7.5 hours! And in case you were wondering, the total number of combinations on a 17 inch Rubik’s cube is about 66.9 quinquagintatrecentillion.
