How do I form my own mirrors using regular cup?

Ok so I'm really pretty and I love mirrors...I have plentifully of them in my house, adjectives over. I've even paid to own my closet doors redone as mirrors.

I notice one day when I be look at the back of a mirror that it looks resembling there is in recent times blackish paint on it, and if you scrape it bad with your fingernail later it's regular glass.

So concluding night I be thinking...if you just painted the outside of your window black would they become mirrored on the inside? Or is there a special thoughtful of paint you must use?

If anyone could help me integer out how to make adjectives my windows mirrors I'd be so so joyful!
