I thought the mercury delay lines were the craziest thing I’d heard about in computer evolution until I learned about using a cathode ray tube as memory.

In a way that is a delay line too, the phosphor decay time allows you to read out the bits a bit later than you put them in. The big advantage is that it is theoretically random access.
