Thames & Kosmos Robotic Dragon Bank Kit — Build a Mechanical Coin Bank (Ages 8+)

Meet the Thames & Kosmos Robotic Dragon Bank Kit, a hands-on STEM project that blends play with learning. Build a mechanical dragon that guards a treasure chest, and watch as a metal coin turns the gears and triggers motion. When you insert a coin, the dragon’s wings flutter and its jaw snaps shut, storing the treasure in the chest. The model is crafted from durable plastic building pieces, and the full-color manual guides you through each step with clear visuals. This isn’t just a toy; it’s a tangible way to explore how electricity and mechanics come together to create movement.

The kit invites curious minds to explore how simple electric circuits power action and how gears translate turning motion into behavioral cues. It’s designed to be engaging and educational without pressure, offering a practical look at cause and effect, timing, and basic engineering tricks that echo real world gadgets. Sensory details abound: crisp snap of pieces, the satisfying click of the gears, the glow of the printed manuals, and the tactile feel of sturdy plastic parts that fit together with satisfying resistance.

What you get

• A BUILD IT YOURSELF coin bank shaped like a dragon guarding a treasure chest, ready for hands-on construction
