The 3×3 Rubik’s Cube is the original and most popular of all 3D puzzles. Collin Burns has been an avid Rubik’s Cube fan for years and can complete one in just 7 or 8 seconds on average. But he just had his best time ever that happened to also break the world record, completing the puzzle in just 5.25 seconds! If only that screaming devil child would be quiet the scene would have been perfect.
