How to put a glass on the edge

I don’t know if this trick is known to the majority, but I’d venture to tell you about it.
So, how to put a glass (bottle) on the edge?

Some sites even sell this secret;)

And the secret is as simple as ever
This focus is always shown on the tablecloth or on the towel (you can use an “exceptionally wet towel” to steam your brains)
We put an ordinary match under the fabric! (better without sulfur) And put the glass so that he leaned on it.

That's all! The girls are amazed, the young men are down!
And the rest is sleight of hand!
