Explore the wonders of motion, friction, thrust, and propulsion! Hydraulic machines use the power of water pressure to carry out specific tasks. Build a fully functional hydraulic crane and introduce children to the fundamentals of hydraulic machines, crane mechanics, pressure, movement, and rack-and-pinion mechanism. Once assembled, kids can push the syringes to direct the crane, lift objects, and move them around. Learn how the power of water pressure can be used to carry out tasks in daily life. It can be painted or colored once assembled. Decorate with your own paints and markers and make it unique!
