Binder clip optics bench!

Friday morning's inspiration, a weekend's work, and I made a classroom's worth of Young's Two Slit Experiment setups for the cost of three boxes of medium binder clips, a pack of 5x7 index cards, and some time spent with painting microscope slides and making very fine cuts in the paint. Oh, and we already had nice lasers, but I found a way to do it with laser pointers, just to be the complete cheapo set. I'll be writing this up for The Physics Teacher's "Tips of the Trade" column.

The last pic is blurry because it's hard to get autofocus to work in a darkened room.
