In 2020 due to Covid-19 unfortunately we had to cancel the handicraft afternoon.
In 2017 (eight participants), 2018 (eleven), and 2019 (twelve) children from 8-12 years 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.
