🕶️Regular sunglasses will not protect your eyes during an eclipse. You need special ISO certified solar viewing glasses.
📸Pinhole projection can be used to safely watch an eclipse. Cover your windows with a small hole to let in outside light.
📦Portable camera obscura can be made using a box, pinhole, and a wall. Face away from the sun and angle the pinhole towards the sun.
🍽️You can use everyday items with small holes, like a piece of card stock, a cracker, a colander, or the leaves on a tree, to project an image of the sun.
🔭You can use binoculars with shade and a screen to safely view an eclipse. Point the big end towards the sun and the eyepiece towards the screen.
