It’s not easy to create a world record by solving Rubik’s Cube puzzles nowadays. Unless you can do it in less than five seconds, with your feet, or without actually seeing what you’re doing.

This year’s European Rubik’s Cube Championship brought together more than 500 participants to Prague last weekend (July 15-17), and competitors faced off in 18 different categories of puzzle-solving. Watch the video above to see just how much you’ve got to practice if you want to go down in the history books.
