'Green' play dough helps kids celebrate Earth Day

The Pittsburgh office's Green Team, sponsored the Moon Township’s 2008 Earth Day Celebration. Employees volunteered their Sunday afternoon to work a "fossil play dough" booth. The "green" play dough was created from used coffee grounds collected from the office mixed with flour, salt, and water. One week’s worth of coffee grounds from the office made more than 90 pounds of play dough. The resulting dough looked like stone and smelled like coffee—and the kids loved it. Using seashells and starfish, the kids made fossils. The team also supplied bagasse (sugar cane fiber) cups for the kids to take their dough home, making the whole endeavor biodegradable and compostable.
