[Leica] Prism fun

[john at chiaroscuro.co.nz (John McMaster)]

Casting my memory back, I think you need directed light (like a full
spectrum laser). Normal light would go in all directions so cancel each
other out. Try it in bright, direct sunlight....

Tomorrow I'll give an 8 year old boy a gift of a small prism , so he  
can have fun making rainbows.  However, after playing with it myself  
for a couple of hours, I can't even get a spectrum myself.
I imagined it wouldn't be too hard to recreate the cover of Pink  
Floyd's Dark Side of the Moon.

Has anyone done this before?  Any tips to pass on to the young lad?

Thanks,

Peter
