This guy is absolutely amazing.
He's a French magician named Yann Frisch, and his performance with cups and balls was a sensation a decade ago and still is today. The act is named "Baltass," and it'll leave you stunned. See if you can figure out how he does what he does:
Frisch was named Champion of France in close-up magic in 2011 and was crowned European champion in 2012. Later that year he became World Champion, and has toured all over the world.
He certainly is a remarkable talent.
