Coriolis Force Experiment Apparatus — Narika

The Narika Coriolis Force Experiment Apparatus allows you to repeatedly observe the Coriolis force visually. The Coriolis force deflects the path of an object moving outward from the axis of rotation on a rotating body (such as a disk or the Earth), and toward the axis of rotation along the body's circumference. It is the effect that induces the swirling typhoons and low-pressure areas seen on satellite images in weather news.

This experimental device demonstrates the presence of the Coriolis force through the changed direction of the water ejected from its built-in tank — students can clearly see the direction of that change, and the demonstration can be repeated as many times as needed.

• Key Features

  •     Visual demonstration — Makes an abstract rotating-frame concept directly observable on the bench.

  •     Repeatable — The experiment can be run again and again for every class or student group.

  •     Built-in water tank — Water ejected from the built-in tank traces the deflected path — no projectiles or complex tracking needed.

  •     Real-world link — Connects the bench-top result to the swirl of typhoons and low-pressure systems on satellite weather imagery.

  •     Cross-curricular — Suits physics (rotating reference frames, apparent forces) and earth science / meteorology topics.

  Applications & Uses

  •     Classroom demonstrations of the Coriolis force and rotating reference frames in physics.

  •     Earth science and meteorology lessons explaining why typhoons and low-pressure systems swirl.

  •     Student practicals — repeat the experiment per group and compare observations.

  •     Science fairs, open days and outreach events where a vivid, repeatable demonstration is needed.

  •     Linking bench-top observation to satellite weather imagery in cross-curricular teaching.

  How to Use- Instruction manual

  1.   Place the apparatus on a stable, level bench and keep the surrounding area clear — water will be ejected during the demonstration.

  2.   Fill the built-in tank with water.

  3.   First eject water without rotating the platform, and note the straight reference path.

  4.   Rotate the platform and eject water again — observe how the direction of the ejected water changes.

  5.   Discuss the direction of the deflection with the class, and repeat the demonstration as often as needed.

  6.   Relate the result to satellite images of typhoons and low-pressure systems, then empty and dry the apparatus after use.
