COThe European Space Agency (ESA)'s educational program, CESAR, has published a guide explaining how to build a pinhole camera using a cardboard box as a safe method to observe the solar eclipse on August 12. This technique allows viewers to see the Sun's image projected inside the box without looking directly at it, reducing the risk of eye damage. The guide provides step-by-step instructions for constructing the device, including cutting holes in the box, covering them with aluminum foil, and creating a small aperture for light to pass through. Experts recommend this simple invention as a secure way to view the eclipse, especially in Spain where it will be visible.
Bias read (Center): The article focuses on a scientific explanation of a safe method to observe a solar eclipse, with no mention of political figures, policies, or contentious issues. It is purely informative and neutral in tone.
