Helium voice

how can I make a high pitched [helium] voice.?

I have a really high voice. Not quite as high as helium though. Lol. But my friends just get a helium filled balloon, and suck some in(not too much or else you'll pass out) and talk really fast. It's fun.

lol thanx.. does it matter what kinda balloon.? because im scared of like, the latex ones. =]

um just get some helium baloons and suck in and then start talking and singing...lol...im an alto...but I can also sing suppranno...

yes it does, youll need a helium ballon, thats full of helium
these are the baloons that stay up and will float away if you dont hold them down
any other ballon is filled with air, and you wont get the voice
