"High Touch High Tech" presents this flight workshop for kids ages 7 and up. Learn about aerodynamics and what makes things fly. Learn about lift and drag as we use blimps and balloons. Launch a rocket and calculate altitude, make a helicopter and discover why what goes up must come down. Brought to you with Federal funds provided by the Institute of Museum and Library Services and administered by the Massachusetts Board of Library Commissioners. Space is limited - you may sign up for this event on or after July 8.
