DIY Pinhole Viewers: A Safe Way to View Solar Eclipses
Introduction
With the upcoming solar eclipse on April 8th, many are looking for safe ways to view this celestial event. One popular DIY method is to create a pinhole viewer. These simple devices can be made from everyday materials and offer a safe way to observe the eclipse without damaging your eyes.
Pinhole Viewer Types
There are two main types of pinhole viewers: card and colander.
Card pinhole viewers are made by poking a small hole in a piece of card. The tiny hole projects light from the eclipse onto a piece of paper or cardboard, creating an image of the eclipse. This method is ideal for children and those with limited resources.
Colander pinhole viewers use the tiny holes in a kitchen colander to project light from the eclipse onto a piece of paper or cardboard. This method provides a larger image than the card pinhole viewer, but it requires a colander with small enough holes.
Safety Precautions
It is important to note that pinhole viewers should only be used to observe the sun during a solar eclipse. Looking directly at the sun at any other time can cause permanent eye damage.
If you do not have a pair of eclipse glasses, a pinhole projector is a safe way to observe the total solar eclipse on April 8th. Simply follow the instructions below to create your own pinhole viewer.
How to Make a Pinhole Viewer
- Card pinhole viewer: Poke a small hole in a piece of card. Place the card between the sun and a piece of paper or cardboard. The image of the eclipse will be projected onto the paper or cardboard.
- Colander pinhole viewer: Place a kitchen colander over a piece of paper or cardboard. The image of the eclipse will be projected onto the paper or cardboard.
Tips
- For a clearer image, use a smaller hole size.
- Hold the viewer a few inches from the paper or cardboard.
- Move the viewer around until you get the best image.
With these simple tips, you can create a safe and effective pinhole viewer to enjoy the upcoming solar eclipse.
