The Sand Foucault Pendulum — a metal pendulum oscillating over a basin of fine sand, on an ABS body. Dimensions: 39 × 16 × 14 cm. Traces complex and unique patterns with each oscillation — variable curve, amplitude, speed, and direction of rotation. An exceptional decorative object at the intersection of science and art.
Unique patterns with each oscillation
The pendulum traces complex curves in the sand — each figure is different depending on the amplitude, speed, and direction of rotation. No pattern is ever exactly repeated.
Infinite variables
Play with the curve shape, amplitude, speed, and direction of rotation — the possibilities for geometric figures are literally infinite.
ABS body + metal pendulum
Robust and lightweight ABS structure, metal pendulum for optimal inertia and smooth, prolonged oscillation.
39 × 16 × 14 cm
Imposing dimensions make it a decorative centerpiece — draws attention and admiration in any space.
Art and science combined
The Foucault pendulum is one of the most poetic scientific instruments — it transforms the physics of motion into ephemeral drawings on sand.
Exceptional gift
For science, art, and design enthusiasts who appreciate the blend of aesthetics and knowledge — an object unlike any other.
Sand Foucault Pendulum — ABS · metal · fine sand · 39 × 16 × 14 cm · infinite patterns
Launch the pendulum. It swings over the basin of fine sand, and its tip begins to trace. First a line. Then the trajectory widens, curves, draws an ellipse, a star, a spiral. Geometric figures gradually appear, with mathematical precision and unexpected beauty. Change the amplitude, alter the direction, vary the speed — and watch the physics of motion transform into ephemeral art with each oscillation. This is the principle of the Foucault pendulum, made visible and tangible on your desk.
| Materials | ABS (body) + Metal (pendulum) + Fine sand |
| Dimensions | 39 × 16 × 14 cm |
| Principle | Foucault Pendulum — pattern tracing in sand |
| Variables | Curve · amplitude · speed · direction of rotation |
| Power supply | None — mechanical energy of the pendulum |
| Usage | Decoration · scientific demonstration · gift |
For more complex patterns: launch the pendulum with a slight rotation at the start (an elliptical rather than linear motion) — the resulting figures will be remarkable Lissajous curves with geometric shapes. The greater the initial amplitude, the more extensive and complex the figures. Regularly smooth the sand between sessions to start with a blank surface.
🎁 The decorative object for curious minds: ABS + metal + sand, 39 × 16 × 14 cm, infinite geometric patterns. An exceptional gift for a birthday, Christmas, office gift, or teacher gift — for any enthusiast of science, kinetic art, and unique design.
Frequently Asked Questions
How does the sand Foucault pendulum work?
The metal pendulum is suspended above a basin of fine sand. When set in motion, it oscillates freely, and its tip traces patterns in the sand according to its trajectory. By changing the amplitude, speed, or direction of rotation at the start, different geometric figures are obtained — ellipses, stars, spirals.
Are the patterns always the same?
No — each oscillation produces different patterns depending on the launch parameters (amplitude, speed, direction, angle). The combinations are practically infinite. Simply smooth the sand and relaunch the pendulum differently to get an entirely new figure.
Does it require electricity?
No — the pendulum operates solely on the mechanical energy imparted during launch. No batteries, no cables. The oscillation naturally lasts several minutes depending on the initial amplitude, then the pendulum comes to a stop through natural damping.
Can the sand be refilled or replaced?
Yes — the sand basin can be filled with any suitable fine sand if needed. Dry, fine sand with a homogeneous grain size will yield the best results for precise and clear patterns.

A Big Help for Dry Skin
This helps so much with my dry skin, especially on my hands. I’ve noticed I need to use lotion much less often throughout the day.

Amazing for dermatitis.
Please never stop making this soap. Not only is it so soothing but it cleansed and balances my PH all over! No irritation very effective. Clean ingredients. Usually, I have to choose between moisture and fully feeling clean. This does both! Lathers and moisturizes. Great size and amazing price. I’m so glad I stumbled upon it. I will be ordering more. I recommend it. Soothes, moisturizes, balances ur skins natural PH and CLEANSES! No fake fragrance, all natural. I strongly recommend

Smells wonderful
I purchased this for my granddaughter. She has eczema on her upper arms. It smells great and lathers up very quickly. It does moisturize the skin too. I will update once we see if it takes care of her eczema. Definitely would buy again.
