Rubik’s cube instructional speech Essay
In 1974, a twenty-nine year old Hungarian named Erno Rubik was trying to solve a structural design problem. He was working on a model that would help him explain a three-dimensional geometric when he finally ended up creating the famous, colorful cubical form we know as a Rubik’s cube!
However, Rubik did not give the cube his name—he called it the “Magic Cube.” It was renamed the Rubik’s Cube by the Ideal Toy Corporation in 1980. Little did Rubik know that his cube would become a sensation around the world with the first world championship held in his native, Budapest, in 1982, with a sixteen year old Vietnamese girl winning the competition, unscrambling the Cube in 22.95 seconds. Solving a Rubik’s Cube requires some study and decision-making. There are a variety of methods used to solve a Rubik’s Cube, but the most popular and the most effective is called the Fridrich method. In the next few minutes, I would like to share with you how to solve the Rubik’s Cube. As I said before, there are many different algorithms and ways to solve a Rubik’s cube. But the one that I have found to be easiest to understand was the Fridrich Method. Now today, I’m only going to explain how to solve one face of the cube due to the limited amount of time. Start with solving the cross. I like to start with the color white, so I will describe the steps according to starting with the white cross. Each side of the cube has a different color center. The center color determines the color of the side. I chose to start with the white center piece on the bottom and the opposite side yellow piece on the top, simply because that’s the way I learned. 1.Look around the cube for white edge pieces, not corner pieces but pieces that outline the cross shape. Move the pieces to the top of the cube around the yellow piece.
• Each white piece of the cross will have a color adjacent to it.
2.You want to match up the, say white blue piece to the blue center piece and the white red piece to the red center piece and so on.
3.Then you want to make sure the white piece is matched up with the bottom white center piece and flip the from face 180 degrees clockwise.
• Do so for every color until you get the all-white cross.
4. Now each white piece should still be matched to the same color center piece.
5.Next you will solve the corners.
•The next 2 steps are the hardest to follow but I will try my best to explain clearly.
6.Look around the cube for white corner pieces. If you have a white corner piece on the top you have to memorize a move. Up clockwise, to 180 degrees, then right goes right back down. This move can be used on any side.
7.Now look at the other color that is adjacent to the white on its side, not top. Match the adjacent color diagonally to its same color by moving only the top layer. Then do the following move: move the right side clockwise, top clockwise, right counter clockwise.
8.Do the same steps with the other white pieces. It could take a few tries to get it right but keep repeating it until you get it.
Now you should have the bottom of the cube solid white and the bottom layer of each side filled with one color.
If you’ve ever tried to solve the Rubik’s cube and given up, I encourage you to try it again now using the Fridrich method I began to explain.

But first let me warn you; as “Cubing” infects people of all ages around the globe, there has actually been a name given for those that are obsessed with a Rubik Cube. They are called “Cubaholics”. Many of real Cubaholics are said to suffer from ‘Rubik’s wrist’ and ‘Cubist’s thumb’! Beware!
