The Flame Tube Project (and Contest Coming Soon!)

Based on the work of German quantum physics pioneer, Heinrich Rubens, I designed this flame tube so propane gas inside the tube flows through holes drilled along the top, and flames are then lit above. I send a sound wave into the tube with a loudspeaker at the other end. When the tube is driven at one of its resonance frequencies, flames form a visual standing wave pattern, as you can see in the picture. Vary the pitch and change the volume to get different patters.

Fire Art in the Gallery?

When you think of fire art, you likely think of art on the desert playa or the Flaming Lotus Girls at Maker Faire. Here’s some fire art worthy of a gallery setting (think of that call to the insurance company). These pieces were presented as part of the 2011 Combustion Art Competition Awards, held at a recent meeting of the Combustion Institute.

Nobody Doesn’t Like Molten Boron

Here’s an excerpt from my new book, The Practical Pyromaniac. It’s a bit different than a lot of the other projects because it deals with making things NOT catch on fire. It’s a pretty simple chemistry project. By the way, it makes paper fire resistant, not fire proof.

Whoosh Boom Bill Gurstelle

Our favorite pyromaniac, Bill Gurstelle, is back, and just in time for the 4th of July. He’s also here to talk about/excerpt from his latest book, The Practical Pyromaniac. We’re always excited to have Bill onboard, not only ’cause he’s a great guy, an epic maker, and a good writer, but being the pyro that he is, you just never know what he’s fixin’ to immolate. Keeps a person on their toes.

Thermite Experimenter’s Online Video Notebook

UCLA chemist Jeffrey Schwartz, whose traditional thermite demonstrations I very much enjoyed at BAMF last week, has compiled what, he quite plausibly claims, is the world’s largest online gallery of thermite reaction videos at his fascinating site Amazing Rust.com. By my count, Jeffrey has there documented, with pictures or video or both, more than 40 different aluminothermic thermite events, smelting eleven different metal oxides including vanadium, cobalt, and titanium.
