Keep it on for one month

1 month? My girl can't wait that long, she wants that diamond ring now :)


Seriously, interesting. As a matter of fact, I have made diamonds in my lab by pinching some pen graphite with a theta pinch. A tiny coil, like 0.1mm, few turns, then discharged a 250V 6800 uF cap trough it, bang. The coil exploded, caused a small EMP. Under the microscope I then saw tiny diamonds, with characteristic rainbow refraction colors.


I made a bigger version and put it on a hill, hoping a lighting flash would strike it. But as usual, when you need one then there's not a trace of rain or storm...

That sounds good! Lightning can cause artificially so:

I saw something similar a few years ago.  It was amazing!  A small hobby rocket carrying a trailing thin piece of magnet wire reeling off of a spool as the rocket went up.  Then....BOOM!  The lighting followed that thin wire down to the ground stake.  Time after time, this worked.

My question is...with all of that energy in that lightning bolt, why does that thin wire not just melt?  Does the lightning begin its trip to ground and once aimed there, if the wire melts and breaks the ground connection, it does not matter?

It was a very interesting set of experiments.

Thanks Franco, I'll try to translate it. Amazing.


Pirate, I guess it does melt and vaporize, but at that time the air is already highly ionized, even plasmized, a highly conductive path.


Which leaves the question, what would happen with the graphite?  :'( Well, just use a big piece...

Fascinating, but I may end up in guantanamo if I start building rockets like that  8) .

That's a cool hobby. If it wasn't for my ongoing UFO construction, I definitely would join the party.  :)


However, I probably will try to pinch me a diamond with a simple fireworks rocket the sooner or later, thanks again for that suggestion.
