Beth Johnson said she brought the 7,300-pound yo-yo Monday to Jacksonville and two hours of tests at Jacksonville Crane and Machinery discovered the release mechanism was not functioning properly, The Florida Times-Union reported Tuesday.
"It's got to be able to return or it's just a waste of time," Johnson's husband, Tony, said. "We want to make sure we can get 80 or 90 feet from that drop."
The couple said the yo-yo needs to be able to go up and down three times to be eligible for the Guinness World Record, which is currently held by a Michigan team that created a yo-yo 11 feet, 6 inches wide.
Johnson said she is aiming to retry the yo-yo Wednesday.
