Be(prism)am
Nice little cubic beamsplitter prism. (Get it?) 12 x 11 x 10mm, it's painted black on (3) sides. Low transmission-about 70/30 or 80/20-but it'll be fine for classroom demos, experimentation, or perhaps souping up your fancy laser device.

Mini-Monster Prism
Optical grade unsilvered glass prism from Uncle's WWII tank periscopes. This one is 2-1/8" on the hypotenuse, 5-3/4" long, and 1-1/2" on each leg. They may come with small non-interfering chips or surface scratches. Great for classroom experiments or for art projects. These are a true surplus find and they will not last forever so get yours today!

Bend It Like Newton
…with this clear-acrylic triangular prism, 25mm x 50mm long (1" x 1-15/16"). Perfect for light refraction lessons--especially for younger kids, since the plastic won't chip like glass will--and for showing how Sir Isaac figured out rainbows way ahead of all the other kids.

See Things Sideways
Through our little black-plastic right-angle viewer. It's a 1-1/4" x 1-1/4" hexagon, and Paul says that if you buy (2) you can see eye-to-eye with yourself, which is a little spooky. Great for a little light spying on the street, and if you find a way to stick it over the lens of a small digital camera, you'll get great candid shots.
