For 2.008 Design and Manufacture II, our team designed and manufactured 50 yoyos based on a time travel theme (a cross between The Doctor's Tardis and Harry's Time-Turner). Each yoyo half was comprised of 4 injection molded parts and 2 thermoformed parts. The yoyos featured a plastic hourglass filled with sand that would continue to spin on a ball bearing after the yoyo was caught.
