Helium as a voice modifier
As you breathe in and out, air flows down your throat and past your vocal cords. Your vocal cords make that air vibrate, creating sound.
But helium is lighter than air. If you inhale helium, those vibrations will move faster than in air. Almost 3 times faster. Those fast vibrations will make your voice sound very high.
Be careful though: inhaling helium can also be dangerous. Helium gas takes the place of oxygen. If you inhale too much helium, you can become unconscious and even suffocate.
