I suppose that most people know that the Apollo 11 crew left a prismatic reflector on the surface of the Moon. One article (in the days before the Internet, so I don't have a URL) claimed that the first time it was successfully hit by a laser beam from earth, 14 photons came back...

Based on this, when I was teaching at a Tech college, I used to have the students calculate the storage capacity of a light beam reflected from the moon, at various bitrates. The calculation is a simple multiplication, but the result made several students at first think that they had come out three magnitudes wrong by mixing up kilo and mega or something like that. (It is a nice introduction to a discussion of windowing mechanisms on high speed fiber links!)

I also used to spend a lecture on historical computing equipment, where mercury Delay line memory - Wikipedia[^] was one of the technologies that truly fascinated the students. This was actually in practical use (as opposed to ICMP and light beam to the moon storage).
