Helium is 6 times less dense than air which means that it travels through your lungs much faster which makes your voice and your vocal chords sound much higher.
helium balloons and make your voice sound weird
it is used to make your voice sound funny
You can use air but it won't float so I would recommend helium. If you suck in helium, it will make your voice sound weird.... Try it!!
The timbre is changed: the cause is the great speed of sound in helium. Every material has a different speed of sound.
Try sucking in helium found most commonly in balloons. Only the balloons that need a weight to keep them down have helium in them - because helium is lighter than air. Anyway helium will make your voice sound high- pitched therefore making your voice sound funny. Helium in big intakes can damage your lungs; but don't worry you would have to suck in a lot to damage them.
make a tuba sound like a flute or get a voice changer...edit the sound on computer,put wax paper over the sound holes...it's a very weird answer...to an odd question
Since helium is seven times lighter than air, when your lungs are full of helium and you begin to speak, the compression waves of the sound of your voice move faster through the helium until they are expelled from your lungs. At that point, the waves are quickly slowed. However, the ear detects more closely bunched sound waves as a higher pitch, such as those moving moving more rapidly through the helium.
yes
The low-tech way would be to inhale a bit of helium, which has a low density, making your voice higher. A better way would be to open the video in some video-editing software on your computer, and then add an effect to the sound of your voice to make it sound higher.
Because its awsome
make your voice weird you must.
Anywhere. Just inhale Helium ;-)
