Hi,
It=B4s not a matter to laugh about what = happen to=20 me
 
I am occasonally do some demonstration = in a=20 vacational school with a simple spark transmitter.
Such a Xmitter can be easy  built = with items=20 from Leybold. Leybold furnised schools physics - store rooms but many = teachers=20 dont know what treasures in there especially for radio.
 
So I built with a high voltage = transformer, a=20 multible spark- gap, 2 huge Leydener bottles ( 2 x 500pF ), a primary = coil ( 10=20 wdg) and multiturn secondary coil as Tesla transformer = connected.
 
There was also a strange looking bulb = which was=20 filled with a unknown gas ( discover later )
 
As I did the first test the transmitter = works as=20 there was a very loud crackling noise in the multiple spark gap, = accomanied with=20 a lot of sparks a blue-ish- red sparks in and arround and from the top = of the=20 tesla coil.
 
So fare so good. that was the = test.
 
Next day ( Professor Ferdinand Braun = Day ), the=20 auditorium was full with students and press, I showed first am simple=20
" Wagnerscher Hammer"  ( it is = similar to a=20 old door clock ) with some sparks at the interruptor.
The response was feeble.
 
Then I pullt out the = surprise.
 
I let dim the room and forced the = students to go=20 mor away and started the Tesla- transmitter.
 
You may imagine what happen with all = that sparks,=20 the noise, the coulors, the smell of ozon and the illuminated gas=20 bulb.
 
In one corner of the auditorium where = suddently a=20 rumor, because all Pc stalled.
 
For me and all Hams, we know what = happend ...=20 beside the sparks where also produced EMF- pulses, strong enough to stop = the=20 processors from work.
 
What would happened, if I would use = more power=20 ?
 
You may know the answer
