Calling all engineers, tinkerers, problem-solvers! Join us to design and build a balloon-powered car, create 2-D and 3-D shapes using only wooden pegs and modeling clay, and form structures out of foam blocks and popsicle sticks. We will lay out the rules and the materials needed, and the rest will be up to you!

For tweens ages 8-12.

Thank you to our summer reading sponsors: UniBank, Mattina Proctor Foundation, Cornerstone Bank, Country Bank, Price Chopper Golub Fund, bank Hometown, Bob’s Discount Furniture, Walmart, the Worcester Public Library Foundation, and the Friends of the Worcester Public Library.
