While I work on captioning, tagging and uploading the rest of my Mediterranean trip photos, try figuring this ‘magic trick’ out. It was performed by the owner of a tapas place in Barcelona.
He wasn’t touching the bottle at all. Just whacked it down hard on the table, with an ordinary napkin.
We tried to replicate the trick later, at another restaurant, but it didn’t work.
Post your theories on this blog (as a comment).
