In a remarkable feat of engineering and determination, James Goh, a 23-year-old student from Cambridge University, has claimed the Guinness World Record for the longest time spinning a fidget spinner on one finger. His impressive record stands at 30 minutes and 34.54 seconds, shattering the previous record by nearly five minutes. This achievement, rooted in both childhood fascination and academic prowess, showcases the blend of creativity and science.
A Journey Back to Childhood
James’s journey into the world of spinning began long before he stepped into the hallowed halls of Cambridge. Like many, he was captivated by the fidget spinner craze that swept the globe in 2017. However, his interest runs deeper than mere nostalgia; it’s a reflection of a lifelong passion for mechanics and design.
“I remember being mesmerised by the spinning top in Christopher Nolan’s *Inception*,” James shared, recalling the moment that sparked his fascination with gyroscopic motion. This childhood enthusiasm blossomed into a serious hobby, one that he has meticulously honed during his studies in engineering.
The Science Behind the Spin
Currently enrolled in the Manufacturing Engineering Tripos, James has applied his academic knowledge to elevate his hobby into a record-breaking pursuit. His spinner, aptly named the “pulsar fidget spinner,” is a product of extensive research and experimentation, incorporating principles from aerodynamics and tribology—the study of friction.
“I used academic papers to inform my experiments and refine my design,” James explained. His innovative approach involved creating 3D models based on data collection, allowing him to experiment in the workshop and fine-tune his creation. The spinner’s design is not just about aesthetics; it’s a calculated balance of physics at work.
“The core is made from lightweight hollow aluminium, while tungsten is concentrated around the edges to maximise kinetic energy storage,” he detailed. This design principle, which increases the spinner’s moment of inertia, is crucial for maintaining a prolonged spin.
Overcoming Challenges
Despite the scientific foundation of his project, James faced numerous challenges along the way. He noted, “There’s no magical, optimal spinning time; you can only get close to it.” The intricate balance between maximising initial energy and minimising energy loss became a complex optimisation problem, pushing his engineering skills to the limit.
James’s record-breaking attempt took place in Hong Kong on December 16, 2025, a city he calls home when not studying in England. After achieving his goal, he reflected on the physical demands of the challenge. “My finger did ache a little bit after holding it in the same position for so long,” he admitted, yet his joy was palpable. “I suppose in a way I’ve taken the fidget out of fidget spinning!”
The Competitive Spirit
For James, the thrill of spinning is not just about the record; it’s also about the competitive edge that drives him. “People often ask why I’m so interested in spinning tops and fidget spinners,” he said. “There’s something hypnotic about them, and their mechanical efficiency is remarkable.” His passion for the craft continues to evolve as he seeks new materials and techniques to enhance his designs.
James’s achievement is a testament to the potential of combining passion with academic knowledge. His journey serves as an inspiration to others, illustrating how hobbies can lead to extraordinary accomplishments when fuelled by curiosity and dedication.
Why it Matters
James Goh’s record is more than just a personal triumph; it embodies the spirit of innovation and perseverance that characterises the best of academic pursuits. As he merges childhood passion with rigorous engineering principles, he exemplifies how the pursuit of knowledge can lead to surprising achievements. His story encourages young minds to explore their interests, reminding us that even the simplest of toys can inspire profound creativity and lead to remarkable discoveries.
