The Newton Free Library will hold its 5th annual STEAM Expo for all ages on Saturday, September 15, 12-3PM, including the soft launch of the Library’s new Makerspace. (You can join the Makers-at-the-Library Meetup to stay up to date.) Last year, over 1,500 attended the Expo, and this year it’s expected to be even bigger. This STEM + Arts Expo is a gathering of tech enthusiasts, traditional crafters, artists, musicians, educators, tinkerers, hobbyists, museums, engineers, and students.
