Introduction: Best Eclipse Viewer Ever!
You'll be out in nature anyway to view the eclipse, why not use your surroundings to make a pinhole camera?
Step 1: Easy to Build, Easy to Make, and Fun. What More Can You Ask For?
Stiff aluminum foil, about 15cm by 15cm square
A small mirror
A hole punch or some method of making a very clean small hole between 3mm and 10mm
Make a hole in the foil. The cleaner the edge the better the image. The large hole lets more light through but is less sharp than a small hole. Because it's an eclipse, you'll see it just fine. Use the mirror to reflect the eclipse through the hole in the aluminum onto a projection surface. The projection should be in a dark place so you'll be able to see it.
That's all there is to it!
Step 2: Set It Up
I used the rocks in the river bed to prop up the parts. If the projection surface is small, you'll need to use the mirror to track the sun's motion during the eclipse. Super hands-on!
Stay safe and keep your eyesight!
