A friend came across a project known as a Flame Speaker. The similarities to a Rubens Tube resonated with me and I was immediately intrigued.

Apparently hobbyists were making these things in their basements around the country, but for some reason the popularity waned and we were having trouble finding many modern implementations. I suppose it’s just a parlor trick anyway.
Well, we did a little brainstorming and came across a fun art project for the magical process. But first we needed to hit the lab and see if we can make something actually work. After a few iterations of testing, we arrived at this version:
Don’t worry, I’ll have more information about what our setup looked like before too long.
