>Imagine you have a color box and a shape box. You fire a random assortment of red and blue chairs and stools through the color box, red chairs and stools fly out one end, and blue chairs and stools fly out the other. Now you know that each object has a 50% chance of coming out blue or red, and a 50% chance coming out a chair or a stool.

>Now, the red chairs and stools fly into a big pile but the blue chairs and stools fly from there into a shape box, where chairs fly one direction and stools fly another. 50% of them fly in either direction

>Then the blue stools fly into a big pile while the blue chairs continue on into a second color box. 50% of these are chairs, as we've said. From there, you'd expect all the blue chairs to come out the blue aperture in the color box, but this isn't what happens. Instead you find that the blue chairs coming in have a 50% chance of coming out as red chairs or blue chairs, in their respective apertures.

>"What the fuck", you might say, and your shock would be justified. My mind would be blown as well. Where the fuck did the red chairs come from? Who knows, but it breaks out understanding of reality and that's why quantum physics are so important.

This is a rough account of how my uncle described superposition to me at his 60th birthday party a few days ago. Is this accurate?
Any science people please confirm, I intend on using this in the future when I have to explain it to people. I'm only in my first physics class in uni so I don't know enough about it yet to know.
