Experience the wonder of mechanics and mathematics intertwined.

Our contraption begins with a series of gears intricately arranged to challenge gravity, lifting balls to new heights with seamless precision. As each ball reaches the apex of its ascent, it's greeted by a meticulously angled ramp, ready to guide it through the next phase of this mechanical ballet.

But the magic truly unfolds when the ramp, filled to its capacity with ten spheres, tips elegantly to the side, a tribute to the timeless principles of weight and balance. Nine balls cascade into a waiting chamber, while a single ball descends onto a lower path—setting the stage for the next round of calculation.

Reminiscent of the abacus, our contraption operates on a beautifully simple decimal system, offering not just a visual spectacle but also a tangible representation of counting and mathematics.
