My Child watched it in Australia 25 years ago ,when my brother send us tapes from Germany. Being an Kindergarten teacher I think this is the best show for Children and Adults. My Cousin once said, that it was the first time she understood the atomic reaction. So many things we take for granted where explained ,that made you appreciate the world and what is in it. Thank you Die Maus and her herzlichen Glückwunsch zum 50 Geburtstag,
