Twelve-year-old Peyton Robertson became the youngest person to win the Discovery Education 3M Young Scientist Challenge with his ingenious polymer sandbag. The sandbag, which Robertson developed for flood protection, contains an expandable polymer that fills the bag when wet. Robertson designed it to be slightly denser than salt water so the bag could withstand storm surges. Robertson has three inventions with patents pending, including a temperature-stabilized golf ball that he designed when he was eight.
