Ruby’s cube

In Sydney, we visited Uncle G and Auntie M, and they (completely unnecessarily) had gifts for the children, all of which were a huge success.

Fainjin loved his little remote-controlled car literally to pieces (must try to fix it for him), Babess was delighted with the little food-shaped erasers which she has decided are perfect for her baby-dolls’ picnics, and Pearl… Pearl got a Rubik’s cube.

Auntie M and I reminisced about having them in our early teens (we are of an age, and a similar level of geekiness), while The Dad waxed lyrical about the mathematical properties.  Uncle G scrambled the cube and handed it to Pearl.

That certainly kept her quiet for a while!

Eventually she got most of one face together – just a couple of squares missing.  I took pity and showed her how to manipulate the cube to get those squares precisely where she wanted them.  Soon (within the same afternoon) she was able to make a full face of any colour that Uncle G nominated… until he started being tricksy and asking for colours that weren’t on the cube to start with!

Babess thought it was Ruby’s cube, even though she wasn’t sure who Ruby was.

I’ll be interested to see whether I have to end up helping Pearl search for “how to solve the cube” pages on the internet, or whether she will actually work it out for herself.  I never managed it, but she just might.
