I suggest you read the explanation from the University of Maryland web
site , i.e, Dick Berg's ideas on this, and it will become pretty clear
this is tough to do.
I investigated doing this a long time ago, and had looked up and read
the Neher, "Light-Pressure Tube", AJP 29, 666-668 (1961) article that
Dick references, and he explains just how good a vacumn you need for
this. I was never able to replicate it, but maybe you can.
PS Dick, congrats on working with the French Embassy! Way cool! Good
luck with the show tomorrow.
