自製液壓爪

My 8-year-old needed minimal help with the syringe assembly, and watching the claw actually grip and lift small toys was fantastic. It’s a solid hands-on way to teach hydraulics without a screen.

The die-cut pieces fit together perfectly, and watching the syringe system lift the claw actually helped my kids understand how hydraulic pressure works. We spent a whole rainy afternoon building it, and they've been playing with it non-stop since.

My 8-year-old had a blast putting the PVC tubing and syringe together, and the cardboard pieces were thick enough to handle a few do-overs. It really clicked when he saw the claw lift a toy car using just water pressure.
