Florida Sixth Grader Invents Sandless Sandbag Dylan Duarte October 28, 2013 Extras Leave it to a Monday story to make me feel woefully inadequate. A sixth grader from Fort Lauderdale, Florida recently won first place in the Discovery Education 3M Young Scientist Challenge for inventing what he calls SOS – Sandless Operational Sandbag. Peyton Robertson is no stranger to floods, having experienced Hurricane Wilma when he was just 4 years old. Wilma and Superstorm Sandy inspired him to create a better sandbag, which he did so by replacing the actual sand with polymer and salt and installing a mechanism that holds them together as the bags expand upon contact with water. Robertson says that he’s “always enjoyed science and math and learning about how things work and making them work better.” This isn’t his first invention, either. When he was 8 years old, he created a golf ball temperature preserver. Two years later, he created retractable training wheels to aid in teaching his sisters how to ride a bicycle.
