Warning labels don't usually help. Labels come on bags of balloons, which are meant to be decorations, not toys, and are not usually printed on each balloon. Yet everywhere they are handing out helium balloons, parents are seen giving one to little Junior, who promptly puts it in his mouth. Which is why I gave up making balloon animals and started doing only face painting when I was a clown. When a balloon is popped it explodes (
as seen here) and can easily be inhaled.
It's like putting the Warning: Hot labels on coffee cups. What happened to common sense?
