The video is about the scam school, a show that was dedicated to the social engineers at the bars and on the streets. In this video they met a couple of friends in a bar and gave them to solve a prank.
For this they used an empty wine bottle, a dime and a cork. They put that dime inside the bottle and closed the bottle with the cork and asked the participants to take the dime first then the cork without breaking the bottle.
They didn't find the solution, at last the host itself solved the prank. He pushed the cork inside the bottle and took that dime, then with a napkin he took the cork too without breaking the bottle.
