Re: [ATM] Vacuuming a Foil

[Ken Hunter <atm_ken_hunter@yahoo.com>]

I've had some success with cutting sections out of
soap bubbles and aluminizing the interior surface.

idea. For now, I'd rather not disclose any more as
there may be important military uses for this
technology and I wish to keep my commercial options
open.
