Learn about TetraKO™, an environmentally friendly firefighting product, in this video from NOVA: “Making Stuff Safer.” Host and technology columnist David Pogue meets with the engineers who designed TetraKO™ to learn how the cornstarch-based gel works as an effective fire suppressant and retardant. The product is a non-Newtonian fluid, which means that it has special properties. When it is first sprayed from a hose, it is liquid. Once it lands on a surface, it turns into a solid and adheres to that surface. In addition, because it is nontoxic, it is safer for firefighters and wildlife than existing chemical fire suppressants and retardants.
