Hi Physics Phriends !

I recently did a sunset demo where I passed a bright beam of white light
through clear water in a ten gallon acquarium tank. I slowly added
non-dairy creamer to the water, stirring thoroughly.  As more and more
creamer was added, more and more blue light was scattered from the beam
("blue sky") causing the "sun" to become redder and redder.  Hint to those
new to this demo, start with very small amounts of non-dairy creamer.

A student asked if I could add something which would scatter red light
causing the sky to be red and the sunset blue. I told him I would post his
question on the Physhare List.  Any suggestions ??    Thanks,  David
