Teen on sub attempted Rubik's Cube record during ill-fated trip, mother reveals

Suleman Dawood, who died at 19 in the Titan submersible that imploded, had planned to film himself solving a Rubik’s Cube at the seafloor some 12,500 feet below the surface of the Atlantic. He had applied for a world record, but it was rejected. His mother and sister now plan to honor his memory by learning how to solve a Rubik’s Cube themselves. Suleman had recently graduated from ACS International School Cobham in England and was skilled at solving Rubik’s Cubes, teaching himself how to do it by watching YouTube videos.
