4 in 1 multipack: Platform Lifter, Scissor Lift, Cherry Picker, Excavator. Make neat simple machines and lift things around the house. Once made - just add water! The simple machine series is designed to introduce hydraulics and machines in a hands-on manner. The models in the multipack teach children about how levers and linkages work. Once made, the models may inspire kids to design machines of their own, and make connections with the engineering of the full sized machines on building sites. No batteries necessary.

*Build your own working hydraulic machines

*Easy to build with all parts pre-cut and ready to assemble

*Quality parts are pegged for added strength

*Great for beginner model makers and future engineers

*Good for school projects and passing food at the dinner table
