Build a simple Marx Generator

Step 7 Spark gaps

Okay, once you had soldered the capacitors and resistors all together, you need to make the spark gaps.
This is what the capacitor's leads are for, making the spark gaps!
Okay, so bend the leads into a "V" shape and bring the ends of the "V" shaped leads about 2 mm (about 0.08 inch) close together.
But do not bring the pointy ends of the leads close together, that will cause a lot of corona discharge, and your marx generator will have very poor performance, or might not ever work...
