In his 47th Street studio, Andy Warhol asked
me one day if we could make him a floating light bulb.
We made some calculations and discovered that it was not
possible with existing battery technology. While working
on the idea, my colleague at Bell Labs found a material
called Scotchpak which was relatively impermeable to helium
and could be heat sealed. The U.S. Army used it to vacuum
pack sandwiches. I brought some of the material to Andy
and then he decided to use it to make clouds. While we
were experimenting with how to heat seal curves and balance
the clouds so they wouldn't fall over, Andy took the material,
folded it over, and made his own version of Silver Clouds.
