His photographs of minuscule grains of colorful sands magnified up to 300 times reveal that sand under a microscope can be a mesmerizing view. Greenberg’s story is a fascinating one. First of all, he invented the high-definition 3D lenses that he takes his pictures on, resulting in 18 U.S. patents under his name.

What does sand look like under a magnifying glass?

Normally, when you look at sand it looks bland and brownish – all the same shape and size. However, Greenberg found that by magnifying it, he was able to expose the shells’ and crystals’ contrasting shapes and rainbow of colors – as well as revealed strange biological organisms – all unnoticeable to the naked eye.

Does sand have fish poop?

Arguably, one of the best parts about visiting a beach is digging your toes in the sand, but have you ever wondered where all these grains came from? Turns out, the majority of sand grains found on white sand beaches, such as those found in Hawaii, are actually parrotfish poop.

Why is sand yellow?

“Iron is a very common mineral on, and in, the Earth”. When the iron minerals are exposed to the air they start to oxidise, and this oxidisation of the iron “is mainly what is giving the sand a yellow-like colour,” says Daniel.

Kaihalulu is one of the few red sand beaches in the world. The sand is a deep red-black, which contrasts with the blue water, the black sea wall, and the green ironwood trees.

Is sand made of fish poop?

The famous white-sand beaches of Hawaii, for example, actually come from the poop of parrotfish. The fish bite and scrape algae off of rocks and dead corals with their parrot-like beaks, grind up the inedible calcium-carbonate reef material (made mostly of coral skeletons) in their guts, and then excrete it as sand.
