Take the cardboard box and cut a 2 centimeter x 2 centimeter hole at one end. Tape a piece of aluminum foil over the hole, making sure it is taut. Carefully use the pushpin or sewing needle to poke a hole into the foil. At the opposite side of the box, cut a small window about 1 centimeter from the end.
Besides, Can we use Aluminium foil to see solar eclipse?
Cover that hole with aluminum foil. Secure the foil with dark tape and poke a hole in the center of it with a pin. Cover the inside of the front side of your box with white paper to make a viewing screen. On a sunny day, stand outside with your back to the sun.

Can you see sunspots from Earth?
Larger sunspots can be visible from Earth without the aid of a telescope. They may travel at relative speeds, or proper motions, of a few hundred meters per second when they first emerge.
What is the safest way to view an image of the Sun?
Pinhole projection is the simplest and safest way to observe the Sun. You’ll get a great view if you project a sunlight coming through a small hole onto a viewing card enclosed in a long box. The smaller the pinhole, the sharper (but dimmer) the image.
What is the safest way to view the Sun and its sunspots?
There are two ways to look at the Sun safely: by direct viewing, with a proper filter over the front of the telescope, or by projecting the Sun’s image onto a piece of paper. They protect the eye against both visible and invisible radiations and the telescope itself against heat.
Can you look at a solar eclipse through a camera?
Solar eclipses may be viewed and photographed, provided certain precautions are taken. You can photograph a solar eclipse with any type of camera: DSLR, COOLPIX or Nikon 1. The longer the focal length of the lens, the larger the images of the sun you’ll be able to make.

Can you look at a solar eclipse through paper?
Pinhole Projection
The simplest safe way to view a partial solar eclipse is to watch the Sun’s image projected onto a piece of paper. … This lets you use a small pinhole giving a sharp image. A much better way to do pinhole projection can be arranged at a window indoors.
What is a sunspot and how can you see one?
Sunspots are dark blemishes on the Sun’s photosphere, or visible surface. They form where the solar magnetic field traps ionized gas and allows it to cool. … If you could view a sunspot by itself, it would appear blazingly bright. But in contrast with its even brighter surroundings, it appears dark.
What do sunspots on skin look like?

A typical spot consists of a dark region called the umbra, surrounded by a lighter region known as the penumbra. The sunspots appear relatively dark because the surrounding surface of the Sun (the photosphere) is about 10,000 degrees F., while the umbra is about 6,300 degrees F.
How can I see the sun without hurting my eyes?
