Ok.. its not a light, nor has anything to with a light, but it is electric...
Any guesses?

Medved has the right idea..

This was a little test/experiment from when I was college-aged .. the idea was to charge up a capacitor & leave it sitting around so someone unsuspecting would pick it up & get alittle shocking surprise
(was never used though..don't remember if it even worked)

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

I do remember well, we did similar things too.
We called it "catch-reflex test": Charge capacitor (some 100 nF) and throw it onto someone unsuspecting, yelling "Catch!". Well, that "reflex" proved to work quite reliably...

We used to charge up small 400 volt capacitors and then sneak up behind somebody and poke their ear lobes with the lead wires...
Megger testers were another favourite...

I see you have the limit of current of 8 mA to shock someone

Pretty, please no more Chinese failure.

I like the idea! Unfortunately I was one of the ones who got 'Meggered' at college

T12/ t17 there's a reason they made heavy magnetic ballasts

If you mean the interrupter arc quenching capacitors for engine ignition, these were about 220nF or so. Usually the same for both battery, as well as magneto ignition systems.

I get enough energy for the day from Pikachu, but otherwise..

The play we had here (introduced by yours truly) is the ordinary 36W Fluorescent choke and 9V battery. If you connect the battery to it, some current will flow. The moment you open the circuit, you get voltage kick across the choke, which is ultimately defined by the current there was (on the order of 100mA with a not so great battery), and remaining resistance connected across the choke immediately after breaing the contact

In dry air (wire pulled from battery terminal) the kick easily exceed 1KV. If you touch the wires when breaking the contact, you get a momentary lightning attack

Eventually the toy found a great use, where we were standing in a circle in series holding hands and taking the kick....



There were the capacitors to, but there we did not do any special charging devices. Provided the capacitor holds the peak mains voltage (which is the case for Y capacitors in electronics equipment, which was our source of tiny mains capacitors), Simply stick it for a second into 230V. The voltage across it will be random between 0 and the peak voltage, depending on the moment you disconnected it

The Y capacitors are also the correct value to give a pichu but not be dangerous, as their shock is the same as if you pull the computer's plug from the wall and touch the pins (its the same capacitors there in the EMI filter)



And finally the PZT spark generator from lighters, for ear lobes..



For the capacitors for bangs, my version here was a high capacity but low voltage capacitor. Those make great spark (and can be improved by appropriate choice of electrode material between which the short circuit is closed)

10000..20000uF 36V (charged from 4 9V batteries) makes nice loud flash but not yet melted copper flying around, and no shock hazard (you dont feel 36V DC normally)...



And for the stuff left on the bench, there was my version which is non electrical at all, but much more suitable for dinners in school trips and such (as it could be prformed in dining room of fieldschools without much special equipment)

Take a bulletin board pin, like the ones with the big plastic head which you can hold in your thumbs or put with the pin pointing up. cover the pin with a "flag" of scotch tape, so that it is not sticky on the outside but covers the tip of the pin

Place the pin in a baloon, enflate it to full size and tie it. Hold the baloon base down, and get the pin to stand upright in the base. Carefully pull the flag off the tip of the pin, to expose the point of the pin

Stand the baloon in this position on top of a cup, or better, make an array of them on a row of cups on the long table... And let the kids pick the baloons
