Anyone here know how someone could make their own solar eclipse
glasses in order to safely view the August 21st solar eclipse??
Was thinking of using multiply-folded metallized film laminate that's
found in common antistatic bags for a filter. AFAICT, 5X foldings of
the 2-ply antistatic bags -- 10 layers in total -- similar to those
described at
http://www.all-spec.com/Catalog/Static-Control/ESD-Safe-Bags/Static-Shielding-Bags
and at
http://multimedia.3m.com/mws/mediawebserver?mwsId=SSSSSuUn_zu8l00xM82xlx_eNv70k17zHvu9lxtD7SSSSSS--
seem to _completely_ block out all sunlight.
All local stores in the general SudoRoom part of the East Bay that I've so
far contacted are already out of stock or are running very low on
manufactured and properly ISO-certified eclipse glasses, e.g., those type
of places listed at
www.yahoo.com/news/where-buy-eclipse-glasses-total-130000190.html
Have also seen the warnings about buying counterfeit glasses, e.g., at
http://abcnews.go.com/US/avoid-buying-counterfeit-solar-eclipse-glasses/story?id=49116565
TY for good suggestions,
