Welcome to my ebay page, a great place to discover unique creations =)
Hi, I'm John, inventor of the "Water-cooled spark gap" - you can find me on YouTube @MadPlasmatist or visit my website at WCSG-Science.com
Thanks for viewing my profile, now onwards, to the future!
P.S. - If you've bought one of my older, original ebay items, they are going way up in value today. Hold on to them! Apparently, I'm a historic figure.
