While I'm preparing a longer post, while E. and T. are working on their telescope, I. still is poorly, I'll show you our optics corner where E., T., S. and I. are doing lots of fun experiments and observations. They like it very much. And T. and E. are happy to show experiments to the girls we - the boys and I - did together.
Die Fotos sind fast alle von T.
T. took almost all the pictures.
