Intended for hands-on learning, it helps explore basic science principles, circuitry and assembly skills. Suitable for individual or classroom experiments and STEM activities.

## Long description

LEAN Sport Creative Spider Kit model 1242 is a DIY saltwater-powered educational toy that allows learners to build a moving spider-like model and observe basic electrochemical propulsion in action. The kit includes the necessary mechanical parts and simple electrical components to assemble a small walking model that is driven by a saltwater cell. Intended for hands-on learning, the kit demonstrates principles of simple circuitry, energy conversion and mechanical motion in a compact, classroom-friendly format.
Advantages
The kit provides a tangible demonstration of electrochemical reaction-driven movement without requiring external batteries or complex power supplies. Parts are designed for straightforward assembly to encourage practical understanding of circuit connections and mechanical linkages. Its compact size and clear learning objective make it suitable for group demonstrations, individual experiments, and guided STEM lessons.
Suitable for
Classroom STEM activities and science lessons
Individual hands-on experiments at home
After-school clubs and maker workshops
Introductory demonstrations of basic circuitry and energy conversion
Key specifications
Power source: saltwater electrochemical cell (uses common salt and water)
Model type: walking spider-like assembly
Assembly: DIY kit with mechanical parts and simple electrical components
Learning focus: basic circuitry, electrochemical propulsion, mechanical motion
Recommended age range: suitable for school-age learners and supervised experiments
How to use
Follow the included assembly instructions to connect the mechanical pieces and simple electrical components, placing the electrical contacts so they interact with the saltwater cell. Prepare the saltwater solution according to the guidance provided, position the model so its electrodes contact the solution, and observe the resulting motion as the electrochemical reaction generates a small driving force. Supervise younger learners during preparation of the salt solution and during testing.
Usage recommendations
Use non-corrosive containers and follow safety guidance when preparing and disposing of saltwater solutions. Perform experiments on a flat, easy-to-clean surface and wear protective eyewear if recommended. For classroom settings, repeat measurements with varying salt concentrations to explore the effect on movement and document observations for discussion.
