Pinhole Sun Viewer – it’s Now or Never for Viewing the Upcoming #SolarEclipse

If you’ve been off-world and are just getting back to terra firma, there’s a Total #SolarEclipse in just a couple days from now! You’ll probably still find eclipse glasses at watch parties and events but they’ll likely be expensive and stores online are sold out. Or if you’re just looking for a last-minute project idea check out the video below from Cody’sLab, spotted over at the SolidSmack blog.

If you’re too busy living on planet Earth to bother with the rest of intergalactic space, you might be surprised at the sudden loss of sunlight August 21. The 2017 solar eclipse will cover the entire contiguous United States and will be the first one to hit the country since June 8, 1918.

To prepare for this once-in-a-lifetime event, why not make your own do-it-yourself sun viewer? While your neighbors will no doubt whip out their digital cameras and video capture equipment, what they’ll be seeing is a tiny blotted out dot of sunlight.

“Even an eleven-year-old can make a sun viewer”, says YouTuber CodyDon on his channel, Cody’s Lab. Using a combination of empty Pringles cans, Dixie cups, duct tape, plastic, a magnifying glass, and a push pin, Cody is able to create a more viable way to see the upcoming eclipse.

  1. My wife found this on Facebook about the Solar event:

    “I’m an optometrist and a mom of three amazing boys. I’ve been in practice for 10 years and have personally managed cases of solar retinopathy, vision loss associated with staring at the sun. During a solar eclipse, the eyes are tricked into being able to stare at the sun for longer periods of time. It only takes a few moments for the eyes to suffer retinal burns that last a lifetime. Please protect your children’s eyes during this amazing natural event. Many counterfeit solar eclipse glasses have been sold. And even if you have approved eyewear, children may peak around the glasses. Pinhole projectors are only good if you’ve constructed it perfectly and use it properly. Your darkest pair of sunglasses is over a thousand times too light to directly view the sun. I will personally watch the eclipse with my children on NASA’s website or on TV, as this is truly the only guaranteed safe way to do so and the risk of blindness is real. Please do your research to properly protect your family if you decide to view the solar eclipse outside.”

    I do not know who to attribute it to except our friends know the eye doctor.

    Once your kids go to the eye doctor when they wake up with haze around the eyes, there is little the doctors can do for them because the damage has been done.
