Portland Rubens' Tube - Music Trials

Physics demonstration built for Advanced Lab to visualize the concept of standing waves. Sound from a CD player is used to create pressure nodes in a tube of propane which creates patterns in the flames. Music includes Journey, Beethoven, and Phantom of the Opera. Construction by Jeff Ryan, University of Portland. 5/1/2008

How long is that tube?

[jbrphy]

see my recent comment for some details

[omegared339]

oh okay thanks. hey could you please tell me what the OD and O.C. stand for?

[jbrphy]

O.D. = Outer Diameter

O.C. = On Center (measurement from the center of one hole to the next)

[donpassyon]

WoW this is the best ive seen, Ive made one but i didnt get nearly as good definition. what s the vital statistics of your tube?????

tube material/ wall thickness/ length?

hole diameter and spacing?

thickness of diafram?

what did you use at the opposite end to the speaker?

.....

cheers

[jbrphy]

Hi there. Not sure of the wall thickness (and the school still has this, so I can't check), but posted some details above. End opposite the speaker was just a metal barb adapter (for the gas hose) and hex busing screwed into a PVC bushing fitted to the main tube.

Dude, this is better than a fireplace. xD

[NeophyteFilms]

the first propane grill to utilize this scientific discovery im buying hahahahaha cant u imagine an ipod dock grill that entertains you while you cook?

proof of how perfect Beethoven's work really is through fire. 

[Nerdule]

Essentially, it's an equalizer made of FIRE.

Well played, sir.

отличный эквалайзер...

[lukasmuller93]

Hi! How do you delivar the gas into a tube? Do you deliver a pure Propan-Butan or is it mixtured with air?

[Pseud0Zombie]

Pyromaniac + Musician = THIS
