The SwissMiniGun is the size of a key fob but fires tiny 270mph bullets, powerful enough to kill at close range. Officially the world's smallest working revolver, the gun is being marketed as a collector's item and measures just 2.16 inches long (5.5cm). It can fire real 4.53 bullets up to a range of 367ft (112m). The stainless steel gun costs £3,000 although the manufacturers also produce extravagant, made-to-order versions made out of 18-carat gold with customised diamond studs which sell for up to £30,000. The gun is banned from being imported into the US - because it's barrel is less than three inches, meaning it is deemed too small to qualify for sporting purposes.

Experts at the National Physical Laboratory in West London made the world's smallest snowman in December 2009. It is so tiny it would be dwarfed by a human hair – at 0.01 millimetres across it is only a fifth the width of a typical strand, and was assembled using tools designed for manipulating nanoparticles. The snowman is made of two tiny tin beads, normally used to calibrate electron microscope lenses, which were welded together with platinum. A focused ion beam was used to carve the snowman's eyes and smile, and to deposit a tiny blob of platinum for the nose. It was put together by Dr David Cox, a member of the Quantum Detection group at the laboratory, who also took the picture.

In September 2006 German artish Bettina Kaminski broke the world record in making the world’s smallest handstitched stuffed teddy bear with moveable head and limbs. It is 5 mm high (standing) and was called Mini-the-Pooh and appeared soon after its “birth” in many international media and websites, even the British TV reported about it. The artist was reportedly very proud that the british newspaper “The Times” reported about her tiny teddy.

Back in 2006, scientists discovered a fish living in forest swamps on the Indonesian island of Sumatra that is only 7.9mm long. The species of fish belongs to the carp family and is called Paedocypris progenetica.It is the world's smallest vertebrate or backboned animal. The tiny, see-through Paedocypris fish have the appearance of larvae and have a reduced head skeleton, which leaves the brain unprotected by bone. They live in dark tea-coloured waters with an acidity of pH3, which is at least 100 times more acidic than rainwater. The previous record for smallest vertebrate was held by an 8mm species of Indo Pacific goby. The UK's smallest fish is the marine Guillet's goby, Lebetus guilleti , reaching 24mm in length.

The Peel P50 is a three-wheeled microcar manufactured in 1962 and 1965 by the Peel Engineering Company on the Isle of Man. It retailed for £199 when new, and currently holds the record for the smallest-ever automobile to go into production. Designed as a city car, it was advertised as capable of seating "one adult and a shopping bag." The vehicle's only door was on its left side, and equipment included a single windscreen wiper and only one headlight. Standard colours were Daytona White, Dragon Red and Dark Blue. The P50 used a 49 cc DKW engine which gave it a top speed of approximately 38 mph, and was equipped with a three-speed manual transmission that had no reverse gear. Consequently, turning in a confined area could only be achieved by pushing, or lifting the car using the handle on the rear and physically pulling it round.

Quay House, is a tourist attraction on the quay in Conwy, Wales. The 3.05 metre by 1.8 metre structure was used as a residence from the 16th century until 1900; as its name indicates, it is reputed to be Britain's smallest house. The house was lived in until 1900, when the owner was a 6ft 3 inch fisherman named Robert Jones. The rooms were too small for him to stand up in fully and he was eventually forced to move out when the council declared the house unfit for human habitation. The house is still owned by his descendants. It stands nearby the Conwy Castle walls and people can enter for £1.00. The upstairs is so minute, that there's only room for 1 bed and a bedside cabinet. Visitors can't walk about on the 2nd floor, but you can view it from the step ladder. There's just about enough room for 1 stove, a water tap, a bedside cabinet and a bed.

This tiny stallion is one of the smallest foals in the world. At just three days old in the photo below, the pinto stallion, called Einstein, is just 14 inches high and weighs only an incredible 6lbs. The diminutive horse was born in Barnstead, New Hampshire, in April 2010. His tiny proportions may be more suitable for a human baby, but they are tiny for a horse, even a miniature breed like Einstein. Dr Rachel Wagner, Einstein's co-owner, claims the Guinness Book of Records lists the smallest newborn horse as weighing just 9lbs. Breeders say that unlike the previous record holder, Thumbelina, Einstein shows no signs of dwarfism - he is just a tiny horse.

Meet Amillia Taylor - or what she looked like on October 24th 2006 , when she was born as the world's youngest surviving premature baby. Amillia was born at a Miami hospital after less than 22 weeks of development. At birth, she was 9 inches (22.86 cm) long and weighed 10 ounces (283 grams). She suffered digestive and respiratory problems, together with a brain hemorrhage. She was discharged from the Baptist Children's Hospital on 20 February 2007.

The Principality of Sealand is a micronation located on HM Fort Roughs, a former World War II Maunsell Sea Fort in the North Sea six miles off the coast of Suffolk, England. Snce 1967, the facility has been occupied by former Major HRH Prince Roy of Sealand; his associates and family claim that it is an independent sovereign state. External commentators generally classify Sealand as a micronation rather than an unrecognised state. While it has been described as the world's smallest nation, Sealand is not currently officially recognised as a sovereign state by any sovereign state. Although Roy Bates claims it is de facto recognised by Germany as they have sent a diplomat to the micronation, and by the United Kingdom after an English court ruled it did not have jurisdiction over Sealand, neither action constitutes de jure recognition as far as the respective countries are concerned.

Mill Ends Park in Portland, Oregon, United States, is a tiny park that was created on St. Patrick's Day, 1948, to be a colony for leprechauns and a location for snail races. It is the smallest park in the world, according to the Guinness Book of Records, which first granted it this recognition in 1971. The park is a circle 2 ft (0.61 m) across, with a total area of 452 sq in (0.292 m2), in a traffic median which in 1948 was intended to be the site for a light pole. When the pole failed to appear and weeds sprouted in the opening, Dick Fagan, a columnist for the Oregon Journal, planted flowers in the hole and named it after his column in the paper, "Mill Ends".
