This video is about a hilarious prank. In this prank two people, while walking on a pedestrian path, pretends that there is an invisible hurdle in the way, and they are knock against it with a loud noise. People coming after the two, stop when they see such a situation and heard the sound. The actors try to go from another point but the same happen again, and finally they act as they are going from beneath the glass. Other people change their way instead of taking any risk.
