For a PrankvsPrank video stunt, London-based twins and filmmakers Jack and Finn Harries of JacksGap fooled random strangers into taking a picture of Jack. Once Jack handed off the camera and the unsuspecting person was purposely sidetracked, Jack would hide behind a large sign while Finn popped up from a second story balcony.
Finn would call down to the person for them to continue taking the photo. It would confuse each person every time! Some thought it was impossible, some just didn’t understand, and some laughed their butts off!
