Can anyone give a better instructional?

that was a nice cut... I wonder how long it takes to do it...

That's not a cup! It's a lip slicer.

shenanigans?
If anything is doing anything here it's heat, rapid temperature change. Acetone does not effect glass in any way.

Better instructions:
Cut a loop of string to fit the bottle as shown, soak in acetone/flammable liquid (slow burning), light and rotate so the flames evenly burn around the string. The string won't be consumed, just the acetone. dunk the bottle into cold water while applying force to break the bottle. If this isn't just complete BS, it will break at its weak point as the temp rapidly changes. ...I still bet its BS though.

everything on the internets is fake

I'm actually going to try this one out, just to see if it's fake or not. The worst that could happen? A broken beer bottle that I was going to throw out anyway. And if it works I can sand down the edges to smooth it off and give my alcoholic friend a great Xmas gift.

I would be interested to know how this goes.

Making tumblers out of beer bottles is pretty easy though... but this is a lot faster than using a glass cutter to chop the top off (if its real.)

Looks real enough, heat plus cold = fracture in certain glasses and crystals.
