The goal of the 2024 Science Buddies Engineering challenge is to build a Rubber band powered car that goes as far As possible but there’s a twist your Score is higher if you use fewer Materials there are also certain rules You have to follow for example your car Has to be a single device you can’t Build a catapult that launches a car you Can’t just push the car and you can’t Use a power drill to wind up the rubber Band there’s also a limited list of Materials you can use to build your car Each of which has an associated cost for A complete list of rules and entry Information check out the related video Or the video description
