A solar eclipse occurs when the moon passes between the sun and the Earth. During an eclipse the Sun, Moon and Earth are in the same line. The Moon partially, or fully blocks the Sun. A total solar eclipse occurs when the Moon completely covers the Sun's disk.
It is very dangerous to see the sun through naked eyes or even any kind of filters. During Eclipse time it would be a wonderful experience if only you could see how the moon covers our sun partially or completely. To make it possible, we need to know how to construct a pin hole camera so that we can safely see the image of the sun on a butter paper.
How to make a pinhole camera
Things required : a long tube about 1meter in length, pin, butter paper / oil smeared paper, a shoe box/ wide box, a sheet of dark paper.
Step 1 : Cover one end of the tube with dark paper and prick a pinhole in the center. Cover the other end with butter paper so that we can see the inverted image of the sun.
Step 2 : make a circular hole in the box so that the tube fits in tightly. This box acts as a protection to the eye and also increases shade so that the pinhole image looks more brighter.
