Make a projector to safely see a Solar Eclipse

Make a projector to safely see a Solar Eclipse

Nepal will witness partial solar eclipse on Thursday. According to BP Koirala Memorial Planetarium, Observatory and Science Museum Development committee, the solar eclipse can be witnessed from 8:43 am to 11:33 am in Kathmandu, from 8:38 am to 11:19 am in Mahendranagar, from 8:48 am to 11:27 am in Bhadrapur. Although this is an annular solar eclipse, Nepal will witness the partial solar eclipse.

Meanwhile, if you are willing to see a Solar Eclipse then one of the easiest ways to safely watch a solar eclipse is to use 2 sheets of cardboard and make your own simple pinhole projector. A partial solar eclipse projected on cardboard. Eclipses can be projected using cardboard.

Project the Sun

Never look directly at the Sun without proper eye protection. You can seriously hurt your eyes and even go blind. Projecting the Sun through a box projector, or projecting using binoculars or telescope, or simply 2 pieces of card is a safe and easy 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:

2 pieces of stiff white cardboard, eg 2 paper plates alternatively, 2 sheets of plain white paper a thumbtack, a sharp pin, or a needle

What to Do:

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.

With your back towards the Sun, hold 1 piece of paper above your shoulder allowing the Sun to shine on the paper.

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.

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.
