Regarding Tesla's hairpin circuit, that has some striking resemblence with a Tesla coil primary we are dealing first with a typical LC oscillation (say 500Khz) and a superimposed much higher frequency oscillation that creates nodes on the "hairpin"
The reason, halogen lamps are used instead of common incadescence is because they can tolarate much more RF+ spikes and light normaly.
Conerning the light bulb under-water, it is a bahaviour of HF current also. YOU must bear in mind HF current s behaviour is radically different that low frequency or direct ones.
Concerning the "hair" thin wire, if you have ever made fuses of your own, you should know that a typical hair-like copper wire can be used up to 2-10 amps fusing.
....
I undestand that most newcomers in the field are attracted by the fascinating aspect of novel for them phenomena. Upon this fact, a LOT of merachants have made big business... just to know.
Best way IMO is to experiment with what you regard as weird, make observations, seek knowledge and proceed.
ps: The bulb in the tap water is 40w halogen lit by a Kacher run at 500Khz (more or less) and not hairpin circuit.
