It makes your vocal cords go to a higher pitch witch reaches the exit of you oesophagus and exits your mouth disturbing the air particles making your voice a higher pitch. when i dummy it down this is the definition. It makes your voice high pitched! It can also make you lose consciousness and die from hypoxia (lack of oxygen) so make sure you just take a sip from the balloon.
Heilum combined with the light material of the balloon make it as light as air making it float.
Instead of blowing normal air (your breath, a pump, etc.) into the balloon, you'd use helium to make it float.

To change passive voice to active voice, identify the object of the passive sentence and make it the subject of the active sentence. Then, identify the subject of the passive sentence and make it the object of the active sentence. Finally, rewrite the sentence using the active verb form. For example, "The book was read by John" (passive) can be changed to "John read the book" (active).
If by this question you mean how can you make your voice change faster, the simple answer is you can't. Don't try to! It is natural for your voice to change at whatever rate it changes at. Their is no average speed, it is all individual.
