The expansive preschool exhibit experience Engineers On a Roll is a combined engineering lab, playscape, and climbing space that offers preschool children hours of active fun while they explore technology, mathematics, and engineering.

Engineers On a Roll’s colorful balls encourage kids to direct, sort, and experiment while the balls remain in constant motion. Long tracks that dip and curve show physics in real-time action. Engineers On a Roll was made possible at the Da Vinci Science Center through a leadership gift from Bob and Sandy Lovett.
