Leonard made this little gem of a scientific educational video for the Corporation for Public Broadcasting in 1975 for the series The Universe and I. The acting’s a bit exaggerated, but it’s all in good fun, as it was used in closed circuit TV in Kentucky public schools. They were filmed in Kentucky. Fun to see Nimoy in his Sherlock Holmes character, and a good science lesson too!
