Phoenix used its robotic arm during the mission's 15th Martian day since landing (June 9, 2008) to test a "sprinkle" method for delivering small samples of soil to instruments on the lander deck. This image from the lander's Surface Stereo Imager shows the amount of soil delivered to the upper end the cover of the Microscopy, Electrochemistry and Conductivity Analyzer (MECA) by the time the test was finished.
