The Brief A group of MSU students have created lightweight shoelaces that won't come untied and are stronger than steel. The backstory:"This grip will not come untied whatsoever and this single knot can pull a 6,000-pound truck," said Madhav Aggarwal. We have invented the world's first shoelaces that never come untied due to activity, weather, or fray." "Athletic shoelaces that never come untied - we make them for different sports with different benefits," he said. "We realized that if they come untied for me then they must also come untied for a pro athlete," Aggarwal said.
