Description

The Celtic Stone (also known as a rattleback) is a semi-ellipsoidal shaped solid object which when spun rotates on its axis in a preferred direction. If spun in the opposite direction, it goes to the stop and reverses its spin to the preferred direction [1]. As the movement of the stone is multidirectional it is a challenge to perform quantitative measurements of its motion characteristics.
The work presents the experimental set-up and the procedure for collecting date of a rattleback motion. Some preliminary results of video measurements performed with a specific metal rattleback and meant to visualize its motion. Attempts to compare the results with predictions based on the numerical model of the situation are undertaken [2].
The advantages and disadvantages of the measurement system will be presented and discussed.
