What you need
- Card Stock Paper
- Aluminium Foil
- Scotch tape or glue
- a paper pin
To make a pinhole camera, take a piece of card stock paper, preferably dark or black in color. Cut out a small 2″ x 2″ hole into the center on the paper. Cut a section of 3″ x 3″ Aluminum foil. Pierce a small pinhole in its center using a pointed object like a pin. Glue the piece of foil over the hole cut out in the cardboard and violaaa! Its ready.
Now just hold the card upto the sun, and hold it up against a wall or a screen. You’ll see its image nicely projected on the screen
Alternatively, if you got a binocular, it makes a great solar projector. All you need to do is to cover one of the objective lens with its lens cap and hold the open lens upto the sun. A nice image of the sun can be projected on a paper screen or wall some distance away
NEVER LOOK DIRECTLY TO THE SUN. DOING SO CAN CAUSE PERMANENT EYE DAMAGE !!!
