Thames & Kosmos Mega Cyborg Hydro Blaster STEM Kit – Wearable Water Blaster & Gripper

Epic water battles meet hands‑on science

Meet the Thames & Kosmos Mega Cyborg Hydro Blaster STEM Kit, a wearable hydraulic powered water blaster and claw built from 180 plastic pieces. No motors or electricity are required—power comes from your hand, delivering a satisfying stream and a responsive grab mechanism that heightens every outdoor clash.

Slide the blaster onto your hand, press the trigger, and watch a jet of water shoot up to 20 feet. Hit the target with precision while another trigger powers the claw to grab objects in your path. The system is designed for fast, fluid action and easy transitions between play modes. The kit can transform swiftly and effortlessly into five distinct shapes: gripper claw, shield, sword, crossbow, and boomerang, keeping play fresh and strategic.
