Build a fully working hydraulic robotic arm from scratch and discover the real science behind it! This advanced STEM kit challenges kids to construct a hydraulic arm while learning how liquids transmit pressure — the same principle used in real-world engineering, from water mills to heavy machinery.
When you push down on liquid in a tube, that pressure travels equally in all directions — meaning a small force can create a much larger force somewhere else. Kids experience this physics principle firsthand as their robotic arm lifts and moves objects using nothing but water pressure.
