Yes, astronomerswithoutborders.org will be taking donations of used eclipse glasses soon. I checked the website today and they didn't yet have the address to send them to.

I actually don't have many left, but will consider donating some.
BTW, I came across an old Life magazine article showing kids making and using the kind of viewer I created some time ago. http://time.com/3737424/solar-eclipse/ I think I made my viewer about 20 years after the kids in the 1960 article. I am sure the world was in color at the time. Anyway, I recall that the stylish head-in-a-box viewer worked well. I could see sunspots with it and I didn't go blind. -- Roger |

[see: http://www.abebooks.com/servlet/Sea...e rs&kn=&isbn= ], which contains instructions--illustrated by Helmut K. Wimmer, the famous Hayden Planetarium astronomical artist--for a large pinhole camera lucida sunbox, but it's the side-view type rather than the "over-the-shoulder" 'hat' type.)
