To answer Krogager's question: Helium would not be effective for the balloons used in these dresses. The balloons used here are latex balloons and the thinness of them allows for the helium to escape too quickly for the size balloons used on these dresses. The artist featured in your article is Ken Stillman of Temecula CA. His website is http://www.BalloonMaster.com
Those of you interested in seeing a Balloon Fashion Show live. You now can this August 2008 in Las Vegas. Please visit http://www.BalloonCamp.com for more information. There will be a balloon dress competition.
You really won't want to miss this event, since it will be the first of it's kind in America. Especially after all the attention given to the China Balloon Fashion Show email.
Wow, is that amazing or what. I wonder what would happen if they used helium...
