Calling down to Russia's mission control (TsUP), Expedition 18 flight engineer Yuri Lonchakov asked for permission for Garriott to use the device, which he said was a clear box with colored oil inside. "It says 'Cube with oil emulsion' in it," Lonchakov described to ground controllers. "At first I didn't understand what it was, [but] this is Thomas Reiter's educational program that was left behind from him," replied a specialist, referring to Reiter's 2006 European Space Agency Astrolab mission during the station's 13th expedition. "This is the cube where they had the oil dyed in bright color. So, if you shake it vigorously then the bubbles break down into small ones." "So yeah, you guys can use it for yourselves. That's no problem at all. Have fun!" radioed the ground. A few minutes later, Lonchakov called down again. "What can we do with it that would be interesting?" "Well, nothing really interesting can transpire from you playing with this thing. Thomas Reiter used it for his educational program. There was one big bubble and if you shake it, it would break down into several small ones." "If by now, it doesn't gather back into one big bubble, then it doesn't really do a thing," offered the ground. Garriott was said to have taken an interest in the experiment to use during educational videos he was recording for the Challenger Center for Space Education. The European Space Agency' website [URL=http://www.esa.int/esaMI/Astrolab/SEMUMEAATME_0.html]described the experiment[/URL] in 2006 as follows: <BLOCKQUOTE>[b]Oil Emulsion[/b] 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.</BLOCKQUOTE> <center><img src="http://www.collectspace.com/review/tma13_reiteroilexp01.jpg" WIDTH="358" HEIGHT="400"></CENTER> <BLOCKQUOTE>[i]Oil emulsion experiment - highlighting how an oil/water emulsion behaves differently in weightlessness and in normal gravity.[/i] Credit: DLR</BLOCKQUOTE> <a name="ham"></a>[/B][/QUOTE]
