DIY Pinhole Camera for Safe Solar Eclipse Viewing

With the upcoming solar eclipse, it's crucial to avoid looking directly at the sun. Instead of eclipse glasses, you can create a pinhole camera using card stock or paper and a sharp object like a sewing needle or paper clip. By making a small hole in one piece and holding it above your shoulder to project the sun's image onto another piece on the ground, you can safely view the eclipse without risking eye damage. Adjusting the distance between the two pieces can change the size of the projected image. For those feeling more ambitious, NASA offers instructions for making a pinhole projector box.

5 DIY Ways to Safely View the Solar Eclipse

University of Calgary associate professor Jeroen Stil demonstrates how to create a simple pinhole camera using household items to safely view the upcoming solar eclipse on April 8. By projecting the eclipse through a tiny pinhole onto a white piece of paper, viewers can experience the event creatively and safely. The pinhole camera works by allowing light from the sun to enter the pinhole, get focused, and then project onto the other side. Stil advises against looking directly at the sun and recommends using the pinhole camera to view the projected image on the screen for a safe and educational experience, especially for kids.

Sun's Daily Journey: Tracing its Path Across the Sky

An image capturing the path of the Sun across the sky in Germany between the summer solstice and winter solstice in 2018 has been featured in a competition by the International Astronomical Union's Office of Education. The image, created by Frank Niessen using a pinhole camera made from a coffee can, combines images taken at different times of day over six months, with each curve representing the Sun's path on a specific day. Gaps in the image indicate cloudy days.

Captivating Solar Eclipse Shadows: A Natural Phenomenon Amazes Americans

Americans witnessed a "ring of fire" annular eclipse on Saturday, and some captured fascinating "eclipse shadows" naturally projected onto the ground. These projections can be seen by creating a pinhole camera or through gaps in the light between leaves of trees. The phenomenon occurs when light passes through a small hole, creating a projection of the eclipse on a surface below. This provides a safe way to view the eclipse without damaging the eyes.
