Gadgets to Go by COSI for ages 7-12 will be held at the Xenia Community Library on Thu., Jul. 27, from 1-2 p.m. The excitement of engineering, force and motion, and mechanics hits the road in this energizing hands-on workshop. We’ll explore energy and how it flows through conductors. You’ll dream it and build it with awe-inspiring Blue Blocks and construct magnetic marble-run roller coasters; program real robots, construct circuits to make music, and even design, build, test, and redesign to create a recycled floating contraption in our five-foot-tall wind tube! Registration required. Call 352-4000.

For a complete schedule of activities, stop by your local library or log on to the library website at www.greenelibrary.info.
