Teenager Suleman Dawood, who died in the Titan submersible, took his Rubik’s Cube with him because he wanted to break a world record says his mother. The 19-year-old applied to the Guinness World Records and his father, Shahzada, who also died, had brought a camera to capture the moment. “He said, ‘I’m going to solve the Rubik’s Cube 3,700 metres below sea at the Titanic’.”
