Hi,
I was pondering the other day about what would happen if i put a smaller 
secondary inside of my current eight inch secondary. Would it boost 
performance or will it simply steal power? I am anxious to try this out but 
i will have to bring my big coil to school. My zip baggie caps are working 
much better than any of the salt water caps i have used before. My coil 
still needs improvement though. My longest sparks so far are about two feet 
long. Not really all that impressive but at least it works. I think that i 
need larger caps as i did not do the math to find out what the capacitance 
of my cap was and i don't have a meter that will measure the capacitance. 
Rotary spark gaps rule! I went from a static gap to a rotary gap and viewed 
a 300% performance increase. I first tried using copper wire as the 
electrodes but it wasn't making my coil perform better. I tried wood screws 
and they worked awesomely. I have found that when the tips of the screws are 
red hot the coil really starts to throw sparks. I think that this is because 
of something to do with the carbon in the steel screw. The heat aligns the 
carbon atoms or something.
                                                     Sincerely,
                                                     Drew Murray
