Floating Glow Display Mod

Floating Glow Display Mod

Admittedly the sign is no longer “floating,” but I modified last week’s Weekend Project, the Floating Glow Display, using an empty CD jewel case, and these are the results. I wanted to be able to swap out the “sign” element of the Floating Glow Display, so the flip-lid of the jewel case allows me to do this (CD covers and inserts are an industry standard 12cm x 12cm).

Hello Poetry Lovers

To celebrate the publication of my new book, The Practical Pyromaniac, the Chicago Review Press (my publisher), is sponsoring a contest to see who can write the most creative Clerihew about fire, scientists, and similarly geeky subjects. For the budding poet, writer, or wise acre with a scientific bent, it’s a great opportunity for creativity!

The Flame Tube Project (and Contest Coming Soon!)

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.
