the dangers of helium balloons are unknown to many people. nowadays children, and even adults, suck the helium out of the balloons to make their voice high pitched, but they are unaware as to how it works. when inhaled, the helium causes your throat to close over. the results can be dangerous. sometimes the result can even be fatal. (learn more at http://www.starvingvendors.com/inhaling_helium.html and see proof at http://www.slate.com/articles/news_and_politics/explainer/2006/06/stay_out_of_that_balloon.html) i would like to stop or even raise awareness to the dangers of helium inhalation.
