This 80-piece construction set lets kids build up to 8 different working models, all powered by pulley systems and snapped together with snap-fit construction. Build a material lift, a stationary bike, a crane bridge, a blender, a construction crane, and a windmill, then see how pulley drives transfer force with reduced friction and boost force or speed. Easy-to-follow building instructions guide the way as kids move from one working model to the next, testing mechanical advantage with real, functioning machines. Designed for kids ages 9 and up, part of Engino’s Discovering STEM line.

• 80 pieces build up to 8 different pulley-driven models, including a material lift, stationary bike, crane bridge, blender, construction crane, and windmill
• Snap-fit construction makes assembly straightforward, no tools needed
• Explores how pulley systems reduce friction and increase force or speed in real-world machines
• Combines hands-on building with theory to reinforce mechanical engineering and STEM concepts
• Easy-to-follow instructions guide builders through each model
