Pyro Board: 2D Rubens' Tube!



Standing waves of fire!

Rubens' Tube is an awesome demo and here we take it to the next level with a two-dimensional 'Pyro Board'. This shows unique standing wave patters of sound in the box.

The pressure variations due to the sound waves affect the flow rate of flammable gas from the holes in the Pyro Board and therefore affect the height and colour of flames. This is interesting for visualizing standing wave patterns and simply awesome to watch when put to music. Thank you to Sune Nielsen and everyone at Aarhus for sharing this demonstration with me! And thanks for having me at your conference.

Music by Kevin MacLeod, www.Incompetech.com "Ice Flow"

I am about to build one of these I have the perforated steel plate all machined and I am going to mig weld the whole box out of steel. My one question is how do I go about mounting the speakers in this so that they don't get damaged? Please any advise from someone who has built one of these.

Would need air holes between the gas ones so that to avoid the flames converging to the center...

somewhere in the middle of the music demonstration the flame started to swirl the only about 8 of the way around the square and it was in between the two access points of the Pyro board. I watch that part more than 5 times by now and it seems to be what happens when too high and low notes switch very quickly, but I would like some one else's opinion.

The appearance of the pyro-board notably from 2:13 to :2:21 looks a lot like depictions I've seen of a quantum field. Since you're looking at sound waves pushed through pin holes, could those holes be used to represent how a wave can appear like a particle?

Very nice. But to those who don't know, be aware of carbon monoxide with this. I wouldn't sit back and chill to a whole album with this going indoors.

Попробуйте над этим квадратом натянуть металлическую сетку.На высоте 1 сантиметр от поверхности.Пламя будет гореть над сеткой.Газ будет также поступать через дырочки квадрата и дополнительно смешиваться с воздухом в прослойке между квадратом и сеткой.
