0,5 Inch Teslacoil
Sparks from the old Coil

This picture contains the final result of 60mm. This happend to be the final sparklenght, because I selled it on Ebay the next day. I wasn´t very satisfied because the lenght not even equals the windinglenght (75mm). Maybe I build a better one some times.

Here you see a light ion-field that builds up from the ground-connected wire
