Kids make great inventors. Just the other day in our @si_invention #SparkLab, a kid invented a doughnut car that works like a gyroscope and "seats nine with liberal leg room." Take that to the U.S. Patent Office, kiddo! ?? Tinkering fans of all ages will enjoy our free Innovation Fest September 26-27 from 10 a.m. to 5 p.m. here at the museum. This is the signature event of the collaboration between @スミソニアン博物館 and the Patent and Trademark Office. Join us! ???? #DCkids #DCfamily #DCevents #InnovationSI
