Detroit Man Breaks Rubber Band Ball World Record with 11,578-Pound Ball
Claude P. Moore started his rubber band ball project in 2015 with just two bands. Over 11 years, he built it to weigh 11,578 pounds, surpassing the previous Guinness World Record. Friends and family helped transport the massive ball for official measurement. The record was confirmed in August 2026 during a public ceremony by Guinness World Records.
