twinrawk asked:
The classic physics experiment involving sound, a tube of propane and fire. Created for Flash Forward 2006, but useful in any case where you are not allowed to have fire. I push through the tube 449 Hz then higher frequencies, then some jazz and then some rock. This is real life sound visualization.

don’t you think this would be amazing at a nightclub or a restaurant or something?
i mean there might be some legal issues
but they could be bypassed….

i can’t believe you used that song by the foo fighters, their stuff from the first album never gets played anymore and it’s my favorite… you rock man!

That is really cool !

Twinrawk, you are awesome.

Next on rednecks with technology…

That was the coolest science expirament i have ever seen. Freaking awesome dude! Wish you would have put something crazy fast though, like guitar shreading or classical stuff…
Thumbs Up!

sure, but first you must guess what will happen to the flames?

twinrawk, great demonstration. Can you make a noise-cancellation Ruben’s tube to illustrate phase-cancellation with fire, and post it? That would be just awesome.
catofgrey, 449 MHz = 26.3 inches, which looks about right.

this is cool. it’s just a shame that if viacom owns any of the material he used to demonstrate this stuff, the video is illegal.

Thanks Kermit!!!!

How is the wavelength being “calculated in the fire?” I see one “bump” (a half sine curve?) being about 12 inches long, so how does 449 Hz map to a 12″ (or 24″) wavelength?
According to my math, the wavelength at 449 Hz is about 2.5 ft.

The standing wave I refer to is a wave that is the same length as the tube. The frequencies that produce no sine curve at the beginning are the wrong length to resonate and return. Some day (for real, just don’t know how long) I will do a second video that is a fun take on resonance.

sine curves of fire!

Physics have never been cooler dude !
Rock on

hi quick question. i noticed that at certain frequencies there were no standing waves. now i was wonderin if it had to do with the fact that its a closed tube and the 2nd 4th and all even harmonics are not possible with a closed tube?

Gives a whole new twist on the “fire” setting available in Winamp’s spectrum analyzer. lol

hah, that’s pretty sweet, loving the Foo Fighters being used too.

I just got finished watching texas ranch house for the first time. DOES ANYONE KNOW IF JARED KEPT THE HORSE AFTER THE SHOW ENDED?

thats shit is funky

A real-life spectrum analyzer using fire.

lighten the fuck up its a joke

it gets badass at 2:01
