meh. I had a diode-capacitor ladder voltage multiplier and a big 800v capacitor bank I pulled out of some old phone equipment that could pretty much belch sparks like that all day.

As the distance between the two electrodes went up, so did the amperage requirements until the batteries couldn't supply the needed amperage or the circuit broke. This almost certainly caused that rear wire connecting battery banks to overheat and break. After that, it probably touched the desk. Path of least resistance suggests it that the batteries then arced to the desk, then caused the scorching as it made it's way toward the metal edging of the desk.

I'll buy a month of TF to any of you who re-creates this experiment, but puts your tongue on the electrode. Results must be posted to YouTube.

You should have seen what we did with the 330 mF capacitors we found in the surplus store. That's right, biatches, one-third of a Farad.

so they built an arc welder with 9v batteries? huh that was a totally awesome way to waste 78 batteries.

I will never in my lifetime own 78 9v batteries at the same time. That's really depressing somehow.

The fact that these kids DID own that many actually depresses me... poor bastages will never get any they don't pay for (and even then, they'll probably get their wallets stolen, unless they keep them in a fanny-pack and don't remove them during the act - which is highly probable)

Seriously? Because voltmeters have extremely high impedence.

My father told me about how he took a tour of a TV station around 1950, and they had a 2-Farad variable capacitor. He didn't know what it was for, so I assume it was for defending the tower from stray raptors.

Dude is lucky.. Does he realize the danger? all the batteries now have 1000+ volts running through them.

possible explosion anyone?

If it was in series, the current would remain the same as that of an individual 9v battery. Judging from the lightshow, it was most likely a parallel circuit. Low voltage, high amperage.

You mean I too can make a boring video and post it online?

I will give it this, most other videos would have spent a few minutes talking about the set-up and problems they encountered in order to give you :13 seconds of meh. So well done there.

he indicated that the batteries are used, he might work for a place that uses equipment which takes these batteries and he collects the used ones. Inventory companies use scanners that take these batteries and I'm sure the they replace the batteries after every use.

Most low voltage DC arc welders start at 24v. In fact, trying hooking up two car batteries in series, then touch them together. Amazing how much spark you can get (it can weld terminals together). 78 nine volt batteries = 702V.. that's a lot of voltage, just not much amps (so you get a nice spark, but no power).

My neighbor has crates of them in his basement. He has to replace them in smoke dectectors yearly in apartments at various complexes. He's in a rock band and has tons of gadgets that require them. Effects pedals and whatnot.

Like 3 milk crates full. Repacked in the boxes the new ones came in.

Not sure if you guys are being deliberately stupid. or not.

It is series, it is a high voltage. You need a high voltage to ionize air - and get a nice arc. Power (energy per second) or brightness etc is Voltage x Current - and at 700 volts just a very small current, say 100 ma would deliver 70 watts, which is more than enough to be quite bright and melt a small piece of wire.

The internal resistance of a 9v battery guarantees that the current will be pretty low, but given that the ld50 for current is somewhere between 60ma and 200ma (not a lot of current though the lower end is for ac) and according to this data sheet http://data.energizer.com/PDFs/522.pdf these guys can supply it - this could be a lethal dose, if you wire your self up correctly.

Yes. I think 9V batteries can source ~ 1A for a short time. Long enough to fry something important.
