Eric M Rogers gave the 1979 Christmas Lectures "Atoms for Enquiring Minds" about atoms, these particles that are too small to be seen with a naked eye, but can be indirectly visualised and explored.

The third lecture "Electrified Atoms", where this clip is from, deals with ions, which are atoms or molecules that have gained an electric charge.
