Pure helium is a medium that allows sound to pass through it more quickly than air, so it makes your voice sound higher pitched (the mechanics are similar to speeding up a video and hearing the sound pitch up). Some gases will do the opposite; most commonly, sulfur hexaflouride, which slows down sound waves.
It could go through your lungs and it tightens your vocal cords and make them move fast and it makes a high note.(It pushes air through your voice.)Thats why helium makes your â¦ voice squeak. How does the helium make your voice high?
