As part of a university module, Goh used academic papers to inform his experiments and help him figure out a formula for a world record fidget spinner.It has lightweight, hollow aluminium at its core and tungsten around the edges to store kinetic energy and help it spin for longer.”It involves a lot of data collection to come up with 3D models, which I then make in the workshop,” Goh said.”Differential equations have helped me a lot to refine the formula, although there is no actual analytical solution, because technically it’s unsolvable.”He said he now had his sights set on more Guinness World Records.
