Project: Make a Pinhole Camera Obscura

Hi -

Here is a fast and fun way to see upside-down images of bright things in your house (and, I guess, the sun). Make your own pinhole camera obscura in - I don't know - 20 minutes or less.

Also, I got to try a free prezo-sharing site called SlideShare.net.



Now, don't go staring into the sun or anything! But it works well if you turn off the lights and look at a candle flame.
