Chinese YouTuber Aboringday builds new weird devices and adds weird modifications on common devices. In his most recent video, he made usually functional yo-yos from objects not commonly associated with the wood or plastic toys. These include fan blades, circular saw blades, ping pong paddles, and clocks.
Some yo-yo bases were easier to make or use than others. Dumbbell plates, for example, were easy to modify but also very heavy. But by far the most challenging project was making a yo-yo out of ice, which required multiple attempts at 3D design and printing before Aboringday got it right. In this process, Aboringday engages in amusing storytelling without ever saying a word.
