HOW TO WATCH THE SOLAR ECLIPSE

Make a projector to safely see a solar eclipse. 

Some people actually see eclipse as the end of the world. At least we had that feeling when we were kids, lol.

Well,

The safest way to watch a solar eclipse is to use two sheets of cardboard and make your own simple pinhole projector.

Solar eclipses can look spectacular, but the Sun’s UV radiation can cause permanent eye damage or even blindness. Make your own pinhole projector to view a solar eclipse.

Project the sun. 

Never look at the sun directly without proper eye protection as this might cause serious eye damage or even blindness.

Projecting the sun through a box projector or binoculars or telescope, or even two pieces of card is the easiest and safest way to view a solar eclipse.

DIY: Simple Card Projector. 

The simplest and quickest way to safely project the Sun is with a projector made from only 2 pieces of card or paper.

YOU NEED:

  • Two(2) pieces of stiff white cardboard Eg, two (2) paper plates.
  • Alternatively, two(2) sheets of plain white paper.

A thumbtact, a small pin or a needle.

What to do:

the concept of a pinhole projector. 

Using two(2) pieces of cardboard or paper, you can project an image of the Sun that does not hurt your eyes.

  1. To make a quick version of the pinhole projector, take a sheet of paper and make a tiny hole in the middle of it using a pin or a thumbtack. Make sure that the hole is round and smooth.
  2. With your back towards the Sun, hold 1 piece of paper above your shoulder allowing the Sun to shine on the paper.
  3. The 2nd sheet of paper will act as a screen. Hold it at a distance, and you will see an inverted image of the Sun projected on the paper screen through the pinhole.
  4. To make the image of the Sun larger, hold the screen paper further away from the paper with the pinhole.

A box projector works on the same principles. It requires a little more time and a few extra items to construct; but it is more sturdy.

KEEP SAFE: 

  • Never look at the sun directly without protective eye gear. Even sunglasses cannot protect your eyes from the damage the Sun’s rays can do to them.
  • Always keep your back towards the Sun while looking at a pinhole projection.
  • Do not look at the Sun through the pinhole, binoculars or telescope.
