Build, squeeze, and grab! Our Hydraulic Robot Claw is one of the exciting activities in the Curious Creator Busy Box for ages 3–6. This step-by-step video shows you exactly how to put it together, from fitting the wooden parts to filling the syringes with water.

This activity introduces children to hydraulics – the science of moving liquids to create movement. By pressing one syringe, water travels through the tubing to power the claw, making it open and close. It’s a brilliant way to explore STEM learning through play.

Whether your child is building along with the video or just curious to see how it works, this hands-on project develops fine motor skills, problem-solving, and engineering curiosity.
