[4] Franklin himself is said to have conducted the experiment in June 1752, supposedly on the top of the spire on Christ Church in Philadelphia. However, the spire at Christ Church was not ...
Researchers have given their lives for this vision; Georg Wilhelm Richmann was killed by ball lightning (1753) when attempting to replicate the 1752 kite-flying experiment of Benjamin Franklin. [96] If an experiment cannot be repeated to produce the same results

A Crookes tube (also Crookes–Hittorf tube) [1] is an early experimental electrical discharge tube, with partial vacuum, invented by English physicist William Crookes [2] and others around 1869–1875, [3] in which cathode rays, streams of electrons, were discovered.
