Sunset Egg

Appearance of egg mimics that of the sky.

Glass egg is translucent, milky white, and contains no pigment- only microscopic particles that scatter light. Short wavelengths of light (blue) have a tendency to scatter off the microscopic particles in the glass; while long wavelengths of light (red and yellow) tend to pass through.  The egg therefore appears yellowish red when held in front of a light source, and blue when held in your hand.
