A Guinness World Records enthusiast balanced a running lawn mower on his chin for 3 minutes, 52 seconds in Idaho. David Rush said he trained for three years and three months before attempting the stunt at the ESPN Road to the X Games event in Boise.
Rush was able to balance the lawnmower on his chin for 3 minutes, 52 seconds while its blades were spinning. A Guinness adjudicator was on hand to verify Rush had defeated the previous record of 3 minutes, 1 second. Rush has broken more than 100 Guinness records in his efforts to promote STEM education.
