The eye-level stack of plastic foam to which Sydney Gralike pointed will make a few bottles of ECoGLOo, an adhesive solution that was developed by Sydney and five junior high school friends.
In 2016, the girls announced their invention that could minimize a pressing global environmental problem. Since then, sought a patent for the process and made 3.5-ounce bottles of the product, which they sold at a plastic foam recycling event Jan. 11 at the Sunset Hills Community Center. They described the invention as an idea "that will really stick."
