Saltwater Capacitor

This capacitor was built using the design published by The Geek Group

The only major difference is that I used nuts and bolts rather than binding posts for the terminals. I also have not yet poured on the top layer of oil. I tested it with my 9/30 NST and a sparkgap, and as long as the sparkgap triggers at a low enough voltage it works fine. Too wide a gap, or completely open circuit and I can here an arc inside.

Here are the pictures:

This is the bottles inside the bucket with the side terminal connected. No saltwater has been added yet

Saltwater has been added to the bottles and the bucket

This is the current functioning state of the capacitor, without the oil added
