no corkscrew, no problem
yes it's in French... but wine transcends all language barriers
not recommended for plasterboard (gypsum board) walls.
We used to do that in college using a folded towel instead of a shoe. You want to hope that there is nothing that is settled in the bottle though, unless you have a strainer as well.
My biggest gripe is this though: how can the person making the video call himself a Frenchman and be without a corkscrew. Impossible.
