How to Make a Stereo Camera
Being able to perceive depth in an object or scene is what makes seeing in stereo (or three diminensions) so different than watching something on a movie screen or on television. People can see 3D because they have two eyes and each can see the same scene from a slightly different perspective to the other. You can make a simple 3D camera that will demonstrate the stereo effect when you look at the two pictures that are taken. The cost will be minimal and the assembly time is less than 10 minutes.

Have the film developed. Place two prints that are of the same scene down on a table side by side. Cross your eyes to cause the two images to become three. Focus on the center image to see the 3D effect.

Tips & Warnings
You can duplicate the effect using two digital cameras and putting the images side by side on a computer screen.
Staring too long at the pictures can give you eye strain and a headache.
