Katy from Kingston, Ontario presents her invention “Wind for Wheels”, an invention for hybrid cars that helps charge the car batteries more efficiently. Mike from Sterling, Ontario presents the “Power Walk” a gadget that is worn in the heel of a shoe and charges batteries while you walk! The stakes are high for Team Naismith when leader Katy gets sick and they are forced to compete in the Water Clock challenge alone against Mike and Team Banting! However, Team Naismith could have an advantage heading into the invent-off if they manage to build the strongest Tough Tote. Will losing Katy give Mike and Team Banting the upper hand? Will Team Naismith pull it together and beat the competition to win the Water Clock Invent-off and the Genius Cup?
