Apparently there are 43,252,003,274,489,856,000 permutations to a Rubiks cube and no I’ve never even come close to completing one? The original cube was invented in 1974 by Erno Rubik and it is widely considered to be the best selling toy ever.
Zheng Weixi is the creator of a cube designed to charge your mobile phone AKA the Magic Cube Charger, it has an internal lithium battery, which whilst your playing with the cube stores all the electro magnetic induction energy generated. So when you need some juice you can just pull the cube upwards and there is a USB slot ready and waiting.
I must say I’m glad that part of it is easy, because if there were 43,252,003,274,489,856,000 ways to get in, I think I’d give it a miss.
