Make Your Own Cluster Balloon

Mr. Christmas Lights writes "'Have you ever dreamed of being carried into the sky by a giant bouquet of colorful toy balloons?' John Ninomiya does exactly that using 50-150 four-seven foot diameter balloons filled with helium ... and sealed with tape (duct?) and cable ties. Folks may recall the lawn chair man who floated up to 16,000 feet, but John takes this to a whole new level and his site has some wild pictures ... and includes the comment 'Kids, don't try this at home!'"

Can not go too high

I remember in a fluid dynamic course we did some balloon calculations, and one conclusion was that baloons are unstable, as they go up, the pressure decreases, so the gas keeps expanding until it bursts. I guess this might be different with a real materials, I don't recall how you model the elastic membrane stuff.
