PS: Maximum eclipse at our location will be 76%, at 10:16amPatrikMany libraries are also providing free glasses, and/or are planning eclipse parties. The Libraries Hosting Eclipse Events map actually shows an eclipse party at the Temescal branch of the Oakland Public Library just down the road from us, on the corner of 52nd and Telegraph. But the Oakland Library website seems to suggest the eclipse party will be at the main branch downtown Oakland. Still, may be worth walking in the Temescal branch and see if you can pick up some free glasses...I was looking into that as well actually (and already put a placeholder for the Eclipse on the CCL meetup page).NASA has a good list Reputable Vendors of Solar Filters & Viewers, and when I checked last week many of these vendors still had glasses available, at around $2 each. If you do wind up ordering some online, please order a few for CCL as well - we can split the cost._______________________________________________On Fri, Aug 11, 2017 at 2:42 PM, aaronco36 <aaronco36@sdf.org> wrote:
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,
