Your eyes are a short distance apart from each other, which gives you depth perception. This is because you are viewing the image in front of you from two slightly different angles. Photographs, on the other hand, are two-dimensional, i.e., flat. There is a type of photograph that can be viewed three-dimensionally: a stereoscopic photograph, which is actually two photographs paired right next to each other. To be seen in three dimensions, the two photographs must be viewed using a stereoscope, which you can make out of a shoe box.
Instructions
1. Mark one end of the box with an X. Place the box on the table with the X mark on the left. Make a mark 6 3/4 inches from the right side of the box. Repeat this mark on the top and back sides of the box.
2. Join the three marks so that you have a line designating where the box is 6 3/4 inches long. Mark the left section of the top of the box with an X.
3. Cut out the two panels marked with X's (the left panel and the left segment on the top of the box). There should be two square flaps on the side of the box that start at 6 3/4 inches from the end of the box.
4. Fold the two flaps of the box to 90-degree angles. Trim off the excess cardboard and unfold the flaps.
5. Mark a rectangle that is 1/2 inch smaller on all sides than a flap on one of the two flaps (your choice). Cut this out to create a frame.
6. Fold the frame piece of the box down, then fold the other flap down to create a backing for the box. Tape along the side of the box and along the open face of the box.
7. Fold the excess piece of cardboard in half. Cut this piece of cardboard to be 6 3/4 inches long. Tape it into the box along the exact center.
8. Flip the box so the solid bottom is facing upward. Point the folded side of the box away from you. On the opposite side of the box, cut a nose-shaped hole into the bottom of the box.
9. Place the nose hole on your nose and identify where your eyes will be. Draw and cut out two eye holes above the nose hole. There should be one eye hole on either side of the divider in the middle of the box.
10. Tape the lenses or transparent film onto the inside of the box behind the eye holes. When you look into the box, you should be looking through these lenses.
11. Insert a stereoscopic photo into the frame at the back of the box. Make sure the center of the photo lines up with the divider inside the box. Look through the lenses to view your 3-D image.
