World's Smallest Sculpture (crushed while being photographed): In April 2015, an artist created what is being called the world's smallest sculpture only for it to be accidentally crushed by a finger while being photographed. Jonty Hurwitz's creations are so tiny they can rest on a human hair and are the same size of an ant's head. The sculptures are less than 1mm tall and are produced via a process called nano-painting. They are too small to be seen with the naked eye so they must be viewed and photographed under a microscope. Mr. Hurwitz used a 3D printing technology to produce them.

The Smallest Bible in the World: You can't really read it, but that's not the point. Researchers at the Russell Berrie The Nanotechnology Institute in Israel engraved the Hebrew Bible on a chip the size of a grain of sugar in order to demonstrate the scale that they work in. The Nano Bible is written on an ultra thin silicon wafer coated in a layer of gold that is less than 100 atoms thick. To engrave the Hebrew letters, the researchers used a focused ion beam to carve away just the gold layer.

Smallest Race Car: At just 100-micrometers wide, this microscopic race car, created by researchers at the Vienna University of Technology in 2012, was built "using a nanoscale 3D printer. Like a conventional 3D printer, resin is used to make shapes, but unlike a conventional 3D printer, the resin is hardened with a laser."

World's Smallest Thinker: In 2007, Korean researchers crafted a microscopic version of Rodin's famed sculpture "The Thinker" (originally sculpted in 1880) using lasers. It's about twice the size of a red blood cell at 20 millionths of a meter high. Muscles and even toes are visible in the tiny model.

World's Smallest Postal Service: At the World's Smallest Postal Service, your letters are written in tiny letters, carefully wrapped, and sealed with a miniature stamp bearing the sender's initial. To make sure the tiny messages don't get lost in the traditional mail, they are packed in transparent envelopes and equipped with a magnifying glass for identifying the mailing address.

World's Smallest Movie: It's not a joke, this movie was really made by moving single atoms around and filming them with the help of a huge microscope.

3D Bull Sculpture: Back in 2001, a team of Japanese engineers created the smallest statue ever – a three-dimensional bull the size of a red blood cell. It was etched in plastic by engineers at Osaka University in Japan.

World's Smallest Working Model Train Set: Measuring a tiny 1/8 inch by quarter of 1/4 inch, this carefully crafted piece of engineering is the world's smallest working train model. The five-carriage train, which is 35,200 times smaller than a real train, nips around an oval route even taking in a ride through a tunnel on its 3/4 inch track.

Microscopic Origami: Shoji Takeuchi of the University of Tokyo, Japan, and colleagues, took the art of origami to new heights – or, technically, new smalls. The team managed to create microscopic origami folds using tissue cultures. They created flat origami designs by cutting thin plastic sheets, then grew cells that crossed the seams of the tiny plates.

World's Smallest Snowman: In 2009, scientists created the world's smallest "snowman," measuring about a fifth of the width of a human hair. Experts at the National Physical Laboratory in West London made the miniature figure which is just 0.01mm across. Far from the thrill of rolling balls of snow around a field to build their masterpiece, it was assembled using tools designed for manipulating nanoparticles.
