@Max: So now you have only a paper bag (and a barrier strip) between your noggin and 170V driving the neons? Good plan LOL
You missed something:
"... I had a paper bag head and on top of the bag I glued a board with a barrier strip.
But yeah, some where over 100V. Might have been ~135V (67.5+45+22.5, if I remember standard B batteries from the late 50s / early 60s. Nowadays we'd be looking at 90 standard C, D, or AA cells, or 100 to 112 AA NiCads. It would start to look like a small Tesla power pack!
The military surplus bag I used for the batteries looks like it was the M6 Gas Mask Carrier bag. I doubt it's around anymore, but it did yeoman service for a year or two as a bookbag I could strap to my bicycle handlebars.

One year for Halloween I made a robot costume. I had a paper bag head and on top of the bag I glued a board with a barrier strip. On the barrier strip I wired up a circuit from Popular Electronics to flash neon lamps in sequence (not randomly). I wired this to several radio B batteriess to get the high voltage needed for the neons, carrying them in a small surplus gas mask bag, and had a normally-on pushbutton switch attached to my gloved right hand. Inerrupting the voltage reversed the direction of the lamps. Two of my brothers and I went out early because our youngest brother wasn't ready, and we were supposed to come back after we went down and up our street. Of course we forgot! We had to give him some of our candy, but we had pulled in a boat-load that night.
It wasn't a Mission Control console but I was proud of it and many people liked the costume. I'm sure that barrier strip with all the parts still attached is either in my basement or my brother's.
Then there were all the things one could do with a large, empty cardboard box ... even as an adult! One year at work, during a partial solar eclipse, I took a very large empty box out to the parking lot, cut a small hole in it, covered the hole with either foil or paper, and made a pinhole projector to watch the eclipse from inside the box, where it was dark. Things were different at work in those days ...
@MAX: A couple of days ago I read about a young kid being suspended for pointing his finger like a pistol and making a "bang" noise...
I'm sorry if this is too far off topic, but regarding the above quote, I just heard a story on the radio this morning about an incident last Thursday in Virginia Beach, VA, which shows the idiocy of a "no tolerance" policy in schools. The radio talk show host called this "Adults Gone Wild." I call it "How Flippin' Stupid Can You Be?"
A middle school student saw a classmate cutting himself with a "razor" and, since there was no teacher in the immediate vicinity, she convinced him that it was wrong to do that, and took the "razor" away from him and threw it in the trash. She then told a teacher. She was put on a 10-day suspension for holding the "razor" and was recommended for expulsion. A local TV station intevened and her expulsion hearing has been moved up, hopefully to consider the whole story and finally bring some common sense to this situation. The "razor" wasn't a razor blade; it looked like one of those miniature segmented blades in a utility knife that one breaks off when it gets dull so one can move a fresh (sharp) blade up into position.
@Max : Did this before you were into short shorts.
I seem to remenber a steel scaffold pole rocket turned into a fragmentation bomb which i and my chum survived unscathed. The garage suffered and we had to learn from our dad's after a bit of corpral punishment, how to remove bits of scaffold pole from the electrical consumer unit and then replace and reconnect the consumer unit and the company fuse.
