And this year’s Oscar goes to . . . chemistry.
On that wonderful night in LA, the red carpet is full of celebrities and fans all eager to hear who wins the gold statue. However, the Oscar statue isn’t pure gold. That would be extremely expensive. The Oscar is actually a bronze statue that is coated with gold.
So how does the Oscar become, well, an Oscar?
To understand we have to think about frog’s legs.
In the late 1700s, Luigi Galvani, who was a professor of anatomy in Italy, was dissecting frogs using a metal scalpel and a copper clamp. He noticed something: The frog’s legs twitched like they were alive! He repeated this a couple of times and they twitched every time.
He found something amazing and called it animal electricity. That is the animal had some supernatural life force inside of it. Galvani wrote up his results and all of Europe embraced this idea.
But, on the other side of Italy was a physics professor named Alessandro Volta. He believed in Galvani’s idea at first, but began to think it was the two different metals that caused the legs to twitch. Volta recalled an earlier experiment by another scientist who had put his tongue between two different coins, and it created a terrible taste. Ends up, that the two metals next each other in a liquid (saliva, in this case) started a chemical reaction.
So with this old experiment in the back of his mind, Volta made sandwiches of two different metals and put them in a jar full of saltwater. Then, he connected wires from this stack of metals to the frog’s legs. They twitched.
What Volta showed is that two different metals together make electricity. He made a battery.
In a battery, electricity flows from one metal to the other.
But what does this have to do with the Oscars?
Well, in order for electricity to flow in a battery in one direction, there has to be metal flowing in the opposite direction. If you were to look at the metal under the microscope you would see that a metal coating is starting to form.
So to make an Oscar this coating process is taken to a much bigger level. The bronze statue is put in a huge chemical tank that has microscopic gold floating in a liquid. Electricity is attached to the statue and the gold particles become attracted to the statue and start to coat it. After a really long time in the tank, the statute becomes the beautiful icon we know today.
So, if you enjoy the Oscars, and many do, you really have frog’s legs to thank.
