Yep, right thru the plastic! You know, with a large plasma burst as when I'm launching the coils, the plasma looks almost like a liquid or a exploding paint splash. This discharge was a like I said a burp. I don't know why it puffed, the discharge should have been larger. But I let her run and the very next discharge is the one that I e-mailed you the photo series of. That is totally freaky! I can allow a little air in or plug it off with the hollow arrow shaft. This hollow electrode allows me to introduce air directly into the discharge. Oh yea, The plasma discharge doesn't diminish even tho I am launching two coils.I didn't have a microwave primary to match the one I had , So I tried to wind one to match, I didn't do a very good job. And LOL the microwave primary was... aluminum! All though I can get a decent lift with the new set. I know it would be better with matching coils. But the matched set of coils still preform as without the second set, Preferably all coils should match.
