After 2017 (July 19, 2017 with eight children) on July 18, 2018 eleven children built their own sundials at KEPLERUHR (design by www.sternwarte-recklinghausen.de). Additionaly the movement of the shadow has been observed at different times. More comfort has been achieved behind the building using the shadow.
