This experiment will be carried out by school pupils (11-14 years old) on Earth and by Thomas Reiter during his long-duration mission on board the ISS. The space section of "Oil Emulsion" will be filmed and downlinked. This experiment will highlight how an oil/water emulsion behaves differently in weightlessness and under gravity conditions respectively. A sealed container holding two immiscible fluids, clear oil and ink-coloured water, will be shaken until the two fluids are slightly mixed. The fluids' behavior in space will be filmed within defined time slots during a maximum of two weeks. The data will be down linked and the results will be shown in a specialized childrens programme on German public TV. The different kinds of segregation that occur during the experiment, in space and on Earth, can be observed and then explained by the teacher. This experiment can form the basis of further physics lessons, (concerning weightlessness, density, other fluid parameters) and maybe even lessons in other scientific areas. The Oil Emulsion experiment was introduced by DLR and is a cooperation between the German and the European Space Agencies.
