Hi all – We are very proud to be able to bring back this video. We had to temporarily remove it due to a few complaints over me (Mr. O) breathing in helium from a balloon at the start and then again right before I issued the warning, which may, to some, be seen as promoting the abuse of inhalents and/or unsafe practices. We have corrected these issues and I apologize for giving this impression.
When we made this video, it was right after the Balloon Boy incident. I was quite surprised how much the media went crazy over this, esp. since it was obvious that the “Jiffy Pop” balloon shown could NEVER have held an 8 year old aloft. I am quite proud of the first responders who did not wait to consider this, but rather reacted with the belief that a child was at risk. That is the sort of response we want to see – act to save a child in danger, then later decide whether or not it is a hoax. Thanks to them for all that they do for us. Enjoy the video!
P.S. – Please remember that while helium is non-toxic, it is not oxygen. We need oxygen to survive. Breathing in too much helium will start to limit the amount of oxygen going to your brain and other parts of your body, potentially resulting in you passing out from oxygen deprivation. Also, NEVER breath helium straight out of a tank. The gas in that case is under great pressure and can cause a pneumothorax, which is a VERY serious condition.
