Rush's third attempt successfully broke the record when he skewered and ate 241 corn kernels in three minutes, breaking the previous record of 236.
"It's a ridiculous talent to have," Rush told the Chicago Tribune. "I practiced skewering a lot to prepare along with the size of the plate, spreading out the corn and best toothpicks to use."
Rush said he has broken a total 83 Guinness World Records, including about 40 that remain unbroken. He said his record attempts are aimed at promoting STEM education.
"A lot of kids don't think they're any good at math or science," he said. "The idea is you can get better at that. If you believe you can get better at something and work hard at it, you can get better at anything."
