Fun With Helium

IN LIGHT OF THE RECENT HOAX ABOUT THE 6-YEAR OLD CHILD WHO WAS THOUGHT TO HAVE GONE ALOFT IN A HELIUM BALLOON, I found this on YouTube. It appears to be real, and looks fun. I guess the risk is, just how high might one go? This could depend on your weight, size of pants and ability of the pants to expand and hold more helium. For me, I’ll stick to making my voice sound like Donald Duck the next time a tank of helium shows up at a party.
