Sunnytech Steel Physics Toy for Kinetic Art Balance

The WJ149 model features a total height of 175mm / 6.89 in, a distance of 175mm / 6.89in between two balls, and a base length of 115mm / 4.53in. Weighing in at 280 g / 0.62lb, it is constructed from silver steel material and packaged in a box.

The package includes 1 toy and 1 base. This model, the WJ156, not only demonstrates the principles of balance but also showcases the Laws of Conservation of Momentum and Energy. Crafted from Metal and featuring a Solar panel, the product has a net weight of 200 g / 0.44 lb.

To play, simply let the steel figure stand on the steel cylinder base and gently push it. The little guy can be positioned in various places, but users should exercise caution to avoid any drops or breakages, as this toy provides a mesmerizing display of scientific theory. Fair warning: it can be highly addictive.

Measuring 6.89in (w)* 6.89 in(H), the toy's size should be verified using a ruler rather than relying solely on visual estimation. The majority of the materials used are silver steel, ensuring a smooth surface that is resistant to rust and fading, maintaining a fresh, new appearance.

Due to the resistance of air and friction, the toy will continue in perpetual motion for only 2-3 minutes. Resembling a one-legged Hercules, the toy features two large steel balls that are held up by two hands, swinging merrily when the wind blows or when touched lightly. Despite its delicate appearance, it is remarkably well-balanced, akin to a tumbler, and can stand in unexpected places, such as on a hand or a vehicle.

Powered by solar energy, the toy requires direct sunlight to function. It cannot operate under interior lighting, such as flashlights or cell phone flashlights. When placed under direct sunlight, the black propeller will run rapidly, rotating the aircraft 360° around the center stand with balance. There is no need to worry about the toy falling off, as it maintains excellent balance. Eco-friendly and powered solely by the solar energy panel, the windmill blades turn smoothly and quietly under the sunlight.
