Is it possible to make a fake golden ring which can light a candle on the push of a button and power it with button cell battery (either coin cell or watch button size)?

I have a fraud guy trying to replicate a miracle. When he is inside his temple, he uses lasers and high tech gadgetry (see here for details). This ring would be a backup for that miracle. I need to know if it would be possible.

    $\begingroup$ @AlexP sounds like an answer rather than two comments. Question is clearly defined and not everyone has a physics/electronics background. $\endgroup$ Mar 16, 2022 at 12:05

1 Answer 1

You can buy the pictured butane lighter ring here

Battery powered lighters also exist which create electrical arcs instead of using combustible fuel.

Combining these two technologies seems like a trivial engineering matter with modern technology.

  • $\begingroup$ But, is the arc lighter powered by a button cell battery or something stronger? $\endgroup$

  • $\begingroup$ That one I think is a lithium battery you charge by a USB port. I think a 2023 cell or something common like that is probably too weak, but maybe a battery of that size using lithium or advanced material science could do it. $\endgroup$

  • $\begingroup$ Also worth noting is that battery voltage is dependent on the material used, and the size determines the capacity for it to discharge that voltage for a long time. Ex: All alkaline cells have 1.5V, but a D cell will last a lot longer than a AAA. Lithium cells are 3.7V. A high voltage is required to create an arc, but if you just need to fake 1 miracle, you don't need high capacity, so you can use smaller cells. $\endgroup$

  • $\begingroup$ Lets just say that I need to fake a miracle for half an hour. Light every candle brought to you. $\endgroup$
