The Marble Run is a series of contraptions that join together to allow a tennis ball to pass from one end to the other. The goal is for the tennis ball to complete the marble run with the least amount of human intervention. Each team is divided into groups, which must complete a section of the device and ensure it joins to the group on each side. In order to succeed, the whole team must coordinate their efforts. #RRI_Egypt https://youtube/watch?v=yOAhEaVRxT0&feature=youtu.be
