Re: [TCML] Streamer development recorded with high speed camera

Hi David,

Great video. Bert gave his incredible knowledge on spark formation and 
propagation which is always a pleasure to read (we love when he gets 
talking about sparks). What I found very impressive in your photo's were 
how the sparks moved after the channel was carrying current. The channel 
moved "up" as would be expected with the heat the current channel was 
dissipating. That was probably the best video of that aspect of TC 
sparks I've seen.

Great job!
Bart
