Eclipse 2017: ​How to Make an Eclipse Pinhole Viewer (There’s Still Time)! by 30Seconds Mom

NASA recommends the use of International Organization for Standardization (ISO) 12312-2 certified eclipse glasses or pinhole projection for viewing the eclipse. If you couldn’t find eclipse glasses, you still have time to make this easy pinhole projection box.

You’ll need:

• box
• aluminum foil
• white paper
• tape
• pin
• knife

Here’s how to make it:

1. Cut a square hole in the bottom right corner of the small end of the box.
2. Tape the foil over the hole.
3. Poke through the center of the foil with the pin.
4. Tape the white paper on the inside of the box.
5. Cut a square hole in the lower right corner of the long side of the box.

Here’s how to use it:

• To view the total solar eclipse on August 21, 2017, stand with your back to the sun.
• Look through the open square hole.
• Focus sunlight through the foil pin hole onto the white paper and you’ll see the total solar eclipse in action!
