Teenager's Rubik's Cube Quest Ends in Tragedy on Titan Sub.
Suleman Dawood, the 19-year-old who died on the Titan submersible, brought a Rubik's cube with him to try and break a world record. His mother said he was a big fan of the puzzle and could solve it in 12 seconds. Suleman contacted Guinness World Records about his efforts before the expedition, and his father even brought a camera to record the moment. Suleman's mother and sister were onboard the support ship when the submersible lost contact. They plan to learn how to solve the Rubik's cube puzzle in honor of Suleman.
