ATD Sand Pendulum Kinetic Tabletop Sculpture — Black 39×15 cm, Natural Sand Pack for Desk Décor

ATD's Sand Pendulum is a tabletop kinetic sculpture that uses gravity and a bead of sand to draw evolving, hypnotic patterns for decoration and mindful focus.

This compact sand pendulum blends simple mechanics with elegant design to create moving artwork on your desk or shelf. The unit arrives with a fine natural-sand packet and a balanced pendulum arm; when set swinging, the bead traces looping ellipses and spirals across the tray. Built from a combination of plated metal, plastic detailing, and an attractive black finish, the pendulum measures 39 × 15 cm and weighs about 700 g — sized to fit office desks, living-room side tables, and bedside dressers.

How does the pendulum make different patterns?

Patterns change based on the pendulum's starting angle, the force you give it, and where the sand meets the tray. Small adjustments to the release point or push can create tighter loops, wider ellipses, or layered spirals.

• Vary the initial angle for narrow vs. broad paths.
• Stronger pushes increase pattern complexity and spread.
• Place sand centrally or offset to alter line density.
• Let it run until the motion decays for layered compositions.

What materials and dimensions should I expect?

The pendulum pairs plated iron parts with molded plastic components and a removable tray filled with natural sand. The black-finish frame and clean geometry make it visually unobtrusive while the metal arm provides stable, repeatable motion.

• Overall size: 39 × 15 cm — fits most desks and shelves.
• Weight: approximately 700 g for steadiness on flat surfaces.
• Materials: plated iron, plastic detailing, and natural sand.
• Package includes a separately packed natural sand pouch.

How do I set it up and maintain the sand pendulum?

Setup is straightforward: place on a flat surface, pour the included sand into the tray, and gently start the pendulum swinging. Maintenance is minimal — keep the tray clean and dry to preserve clear lines and avoid clumping.

• Place the unit on a level table or desk for accurate patterns.
• Pour the supplied sand evenly across the tray before use.
• Start with small pushes to learn how different motions affect designs.
• Wipe tray with a dry cloth; avoid water to keep sand free-flowing.

Who is this for? The ATD Sand Pendulum suits anyone looking for low-maintenance kinetic décor, from designers and creatives seeking a desktop focal point to office workers who want a calming visual diversion. It's also a thoughtful gift for students, teachers, and science-curious minds who appreciate simple mechanical beauty. Use it as a conversation piece in living rooms and home offices, or as a tactile aid for short mental breaks during work sessions.
