Everyone who plans to look skyward when the solar eclipse sweeps across the United States today should have the proper protective eyewear, or risk lasting blind spots. If you don’t want to spend your hard-earned money on those fancy glasses, take a look at a less expensive way to see it and keep your eyes safe.
Here’s how you can make a pinhole camera to watch the total solar eclipse:
Step 1: To make a pinhole projector, take a sheet of paper and make a tiny hole in the middle of it using a pin or a thumbtack. Make sure that the hole is round and smooth.
Step 2: With your back towards the Sun, hold one piece of paper above your shoulder allowing the Sun to shine on the paper.
Step 3: Now, the second sheet of paper will act as a screen. You can hold it at a distance, and you will see an inverted image of the Sun projected on the paper screen through the pinhole.
Step 4: To make the image of the Sun larger, hold the screen paper further away from the paper with the pinhole.
The total eclipse of the sun is considered one of the most spell-binding phenomena in nature but it rarely occurs over a wide swath of land, let alone one of the world’s most heavily populated countries at the height of summer. There hasn’t been a total solar eclipse in the contiguous US since 1979. The next total solar eclipse won’t happen in the US until April 8, 2024. Outside of the US, the next one will be visible in Chile and Argentina on July 2, 2019.
