The wood frame is secured by the string, but the string is being twisted. Shouldn't the cg of the glass/ frame combo be moving up/down due to the twist being imparted by the twisting/ untwisting string?

Would that matter, because it's the downwards force that is holding everything together?

It would imply the cg of the entire assembly is in motion, causing it to want to tip. Unless the cg is moving up/ down exactly over the contact between the wrench and bottle. And that's more impressive.
