A more faithful analogy: I have two boxes with a small hole and ball inside.
If I look through the holes, I will see that one ball is blue and the other is red.
If I touch them through the holes, I will feel that one ball is hot and the other is cold.
However, I cannot look and touch at the same time. And once I check the color or the temperature of one of the balls (so I know it for both) the link is broken.
If I look first, I’l see that one is red and the other is blue. But if now I touch them, each one will by hot or cold with 50/50 probability. Finding the temperature of one doesn’t tell me anything bout the temperature of the other. And when I touch a ball I don’t know its color anymore: if I look at it again it could be red or blue with 50/50 probability.
