July 19, 2011 Magnified Beach Sand
 Beach sand magnified to 250 times its real size Here is some amazing microphotography by Dr Gary Greenberg who shows how beach sand grains look magnified to 250 times the real size. This crystal of sand on the image below (in the middle) is surrounded by bits of coral, shell, and volcanic material. http://todayilearned.co.uk/2011/07/1...ize/#more-2283
