David Rush, who has broken nearly 250 Guinness World Records to promote STEM education, previously held the same record, and aimed to recapture it by balancing for 1 hour, 12 minutes and 40 seconds. Advertisement Rush said he was dismayed to then learn the record had already been beaten with a time of 1 hour, 13 minutes and 25 seconds, invalidating his attempt by just 45 seconds. Rush managed to beat the newest record, set by Spanish man Christian Roberto Lopez Rodriguez, with a time of 1 hour and 35 minutes. The serial record-breaker said he ended the attempt because "the pain was too great and I took the guitar off my chin. That was a lesson in pain."
