This instructable while not the most asthetic ever made is purely functional. It will help you see a solar eclipse with your eyes and in my opinion is better than a pinhole camera or monocular setup.
Step 1: Supplies
Any boxes can be cut to fit I used mostly a "wheat snack box" from a popular Dollar store, Duct tape(god bless Nashua), welder helmet replacement lenses( Home hardware store sells for less than 2 bucks.), exacto knife.
Step 2: Cutting and shaping taping and viewing
this part is pretty self expanatory you can see I took the boxes and slowly made cuts to fit over my eyes comfortably. Dont forget an extra cut for big noses. Then we cut a rectabgle smaller than the total glass size. Next tape up any seams, no matter how small and secure the glass inside with a little clear tape around the edge and Viola!
Step 3: Enjoy
You are done! As I said not the most attractive but we had fun making. You could attach elastic and be hands free, etc. I kept it simple so expand on your own. That's half the fun anyway. The last photo is just the sun not an eclipse but it gives you an idea and the camera made it shinier than normal. The actual image is a greenish circle.
WARNING: I feel silly saying this but staring into the sun is not without danger. That massive exploding ball of gas that a little closer would scorch the planet is bright. Do not use these to look for extremely long periods of time, and if it makes you nervous use the other methods out there. Treat God's creation (the sun and your eyes) with some respect. Don't be stupid, the world has enough of those out there. Thanks and enjoy.
Step 4: Decorate
Steampunkish eclipse viewing this is contact paper that resembles wood.
