Here's a possible kid's school DIY project for acheiving EVO effects.

At one of Greg Volk's NPA conferences I was demonstrating x-ray output of common light bulbs (some incandescent bulbs lack the usual argon fill, instead containing vacuum below 30 microns.) When excited by a "violet ray" hand-held Tesla coil, the internal space does not glow, but their glass will produce dim green surface-flashes from electron impact; cold cathode emissions from the filament supports. A GM counter can detect the soft x-rays, if the probe employs an alpha window.

I bought several aquarium bulbs (the long transparent type, w/tungsten filament.) Several were placed in an otherwise empty microwave oven, supported upright on a plastic stand. The oven was only operated briefly, up to 10sec max., while trying to detect x-ray counts through the oven door. Note that empty microwave ovens produce high voltage RF, tens of KV on metal parts, easily enough to trigger corona discharge from sharp needles or from the edges of torn metal foil. Several bulbs were used at one time, so that one or more would happen to be located in a high-field antinode.

Days later I noticed that one of the bulbs was ruined: when excited with a hand-held Tesla coil, no surface-flashes appeared on the glass. The bulb acted as if full of air. Several other bulbs were similar: they now produced violet glows of various brightness, indicating air contamination at different pressures. (Normally these bulbs produce no visible gas discharge when excited, only producing green or blue flickers on the glass surface.) Also, two bulbs would produce sodium-yellow flashes within the violet gas discharge, when the tip of the Tesla coil was swept across various locations on the glass. (Possibly a spark was passing through a micro-fracture in the glass, vaporizing some sodium.)

Months later, I found that the gas in more of the bulbs would no longer glow at all, and their enclosed filament-supports would exhibit the type of thin white sparks expected at 1atm pressure.

I imagine that the original microwave-oven treatment had drilled microscopic holes through the glass. The bulbs were slooooowwly leaking at various rates, and filling with air over a span of weeks. Note that in these particular bulbs, the filament-supports are sharp iron wires with tips adjacent to the inner glass surface, with some tips visibly touching the glass.

So, if we "nuke" an aquarium bulb, its sharp iron internal wires may be emitting streams of EVOs which perforate the adjacent glass, causing a very slow leak. The glass bulb, with vacuum on one side, accidentally forms a "witness-plate" for detecting EVO strikes producing micro-perforation through the glass bulb.

Ah, if only Scott Little knew this trick back in the day. They might have taken KRS seriously!
