President Obama Had a Blast at His Last White House Science Fair

The Girl Scout Troop #1484 from St. Louis, MO, shared some laughs with the president while describing their project — a bin called Eco Bin that can dissolve styrofoam (which can take hundreds of years to decompose) when it's mixed with water. As a result of this experiment, they discovered a sticky substance that they bottled for art projects and are calling GlOo. They've won state awards and a chance to compete for the Global Innovation Award and are now pursuing patents for both projects.
