Stem Night

Tonight was the STEM show at our granddaughters' school. There were so many cool exhibits, including the Science Fair Projects winners. Ava, one of our granddaughter's best friends nailed her project.
Our SIL was one of the exhibitors. He had a 3D-partially printed self-driving car, an AI robot that simulated HAL from the movie 2001: A Space Odyssey, and a circuit board that the kids could program. His exhibit was a huge hit. (extra)
