Making a Camera Obscura

In this lesson we made a Camera Obscura. To make this we needed to have:

• Pringles Tube.
• Thumbtack.
• Scissors.
• Masking Tape.
• Aliminium Foil. 

1. Take the plastic lid off the Pringles® can and wipe out the inside. (Save the lid!) 
2. Draw a line with the marker all the way around the can, about 2 inches up from the bottom. Have a grown-up cut along that line so the tube is in two piece 
3. The shorter bottom piece has a metal end. With the thumbtack, make a hole in the center of the metal.  
4. We're going to use the plastic lid as a screen. If your lid is clear, you may need to apply a piece of wax paper, white tissue paper, or vellum to the lid to act as a translucent screen. Put the plastic lid onto the shorter piece. Put the longer piece back on top. Tape all the pieces together. 
5. To keep light out of the tube, use a piece of aluminum foil that's about 1 foot long. Tape one end of the foil to the tube. Wrap the foil all the way around the tube twice, then tape the loose edge of the foil closed. If you have extra foil at the top, just tuck it neatly inside the tube.
