#### Transcript

Hi, I am Bob Burton, Rubik's Cube Expert, and I am teaching you how to solve a Rubik's cube. First I will show you how to assemble your Rubik's cube and disassemble your cube, and prepare it for speed cubing.

The first thing you want to do is to be able to take a Rubik's cube apart. You can take it apart by first moving one layer 45, putting your finger underneath an edge, and popping it out. Sometimes it may take a little bit of force with the new cube, but its not as hard once you play with your Rubik's cube a little bit. The corners right next to it should follow easily. You can use silicone lube or silicone spray.

This is an example of silicone lube that comes with some Rubik's cubes that you order online. You can spray this by just taking your finger, pushing the lube to inject the lube into the puzzle, putting the pieces back where they came from; first the corners, then the edge, which may take a little bit of force to put in, and then scrambling your Rubik's cube to work the silicone into the puzzle.

What this does is it makes the Rubik's cube easier to use so that the layers turn more freely. You can also use silicone spray as opposed to this lube that you can obtain from any hardware store or auto part store. Next step is the first layer of the Rubik's cube, we will start with the cross and we will move on from there.
