Talk:Balloon
From Academic Kids
Fails to mention original balloons were dried bladders of animals. --Daniel C. Boyer
I don't know how much detail we should go into on Zeppelin-type craft, but perhaps there should be a mention of hydrogen, because helium hasn't been the only gas used in balloons or balloon-type vehicles. --user:Daniel C. Boyer
Helium voice: I think this article is wrong about the cause, but I'm not certain, so I won't edit yet. Scientific American (March 1987) says that the vocal cords vibrate at a slightly, but not significantly, higher frequency in helium, but that the real cause is the change in the resonant frequency of the vocal tract. This is determined by the speed of sound within, which is significantly different in helium than in air. The vocal cords are not finely tuned like violin strings, but are vibrating flaps of skin that create a sound more like noise than a pure tone. The noise is filtered by the acoustic response of the vocal tract to produce formants (the tones used in speech).
I just found a detailed explanation at http://www.phys.unsw.edu.au/PHYSICS_!/SPEECH_HELIUM/speech.html. This backs up what I just said. Now I am going to edit the article. -- Heron
These balloons are often, incorrectly, called Mylar® balloons.
This sentence implied that there is a more correct name for this kind of balloons or Mylar balloons mean something else. Without further explanation, this extra qualification (incorrectly) seems really odd and out of place. I plan to remove it if no one provides an explanation soon. -- Kowloonese 22:54, 23 Nov 2004 (UTC)
Added sexual fetishm with balloons.
Mylar or not Mylar?
the article says: “Beginning in the early 1990s, some more expensive (and longer-lasting) helium balloons have been made of thin, unstretchable, impermeable metallized nylon films. These balloons are often, incorrectly, called Mylar® balloons.”
So what is it? Mylar or Nylon?
