Students from the Israel participated in a giant yo-yo competition.
The bouncy event allowed students to test their knowledge and creativity by designing and building large yo-yos. The competition looked for the yo-yo that would reach the highest point after being released from a 100-foot (30 meters) tall crane. The idea with the yo-yo was to convert the potential energy to angular momentum of the yo-yo. The winner of the competition designed and built a small and sleek yo-yo, resembling an automobiles flywheel.The engraved yo-yo scored highest marks after the judges calculated the height of its initial ascent. The winning team received 3,000 U.S. dollars for winning the competition.
