The elimination of
Nick Nelson leaves seven competitors in the running for Canada's Greatest Know-It-All Season 1. Additional information provided about the competitors includes: Dave working on a project to send his cell phone into space in a home made device to act as a space camera; and Dan having a side interest in performing improvisational comedy. For the first time, the competitors will be competing as individuals, with the loser of each of the two challenges automatically sent to the danger zone for potential elimination. The first challenge, using a WWII Lancaster bomber, is to bomb a target on the ground, namely Daniel's limousine. The competitors are provided such information as plane speed, plane altitude and horizontal distance of the limousine from the edge of the marked area. From the ground, the competitors, in turn, provide the verbal drop code to the bomber aboard the plane. The losing contestant is the one whose bomb lands furthest away from Daniel's limousine. The second challenge has the competitors being taught all about reptiles and arachnids from expert Dr.
Andre Ngo, which they must then teach in a ten minute lesson to a bunch of elementary school aged children. The subsequent lesson must include picking up one of the animals, which may be difficult for any that has an all too common phobia to snakes or spiders. Dr. Ngo and the students vote on who is the losing competitor. The danger zone challenge has the two competitors building three aircraft in three hours - one using plastic, one using Styrofoam and one using cardboard - each to a minimum specification. The winner of the challenge is the one whose three planes fly the farthest in total. Both danger zone competitors may get a reprieve from elimination if they can beat a third last minute competitor, namely the other five working as a team.
