Granular materials accompany us from early childhood days - but they still retain lots of unsolved challenges for grown-up scientists and engineers. They can exhibit states similar to gases, fluids and solids. So far, most experiments and theoretical investigations focussed on spherical or irregularly shaped particles.
We study a granular gas of elongated cylindrical particles a few millimetres in length under microgravity conditions. Our fully automatic setup consists of a translucent box with shaking walls, which is monitored with digital cameras from two perspectives. We will present first results from our sounding rocket flight. From the video data, the three-dimensional motion of the particles can be reconstructed, to analyze typical statistical quantities of the granular dynamics.
