Throughout history, many groundbreaking discoveries and inventions have been driven by curiosity. The desire to explore new possibilities and gain knowledge has been a fundamental characteristic of humans that has propelled us forward.
Have you ever wondered what might be hidden inside random objects? If so, there’s no need to grab a knife or scissors because there are people around the world who have already done the cutting and documented their findings. This extensive list includes a variety of objects such as bullets, hockey helmets, pearls, and baseballs.
If you’ve ever been curious about the inner workings of everyday objects, take a look at the pictures below and indulge your curiosity. Let us know which ones you find most fascinating!
1# Fragmentation grenade
Credits: karmicviolence – This type of grenade got its name for a reason – such hand grenades send out lots of very fast and very small fragments when they explode. Its body is usually made of a hard synthetic material or steel – the materials provide some fragmentation as shards and splinters. However, in modern grenades, a pre-formed fragmentation matrix is often used
2# Canon camera
Credits: Leotopia – Back in 2014, the very first Canon camera celebrated its 80th birthday. At first, the camera was called Kwanon and it was named after Kwannon, the Buddhist goddess of mercy. The engineers hoped this would entice the god to, “share her benevolence as they pursued their dream to produce the world’s finest camera.”
3# Cactus
Credits: Scout6feetup – There are approximately 2000 different species of cactus and they differ in size, shape, color and their type of habitat. Obviously enough, cacti have spines instead of leaves. The spines have two major functions: they prevent loss of water via transpiration and keep the plant safe from animals. What is interesting though, is that certain cacti produce substance called mescaline which induces hallucinogenic effects.
4# Subsea power cable
Credits: sverdrupian – It is essentially a transmission cable for carrying electric power below the surface of the water. Such cables are usually carrying electric power beneath salt water – hence the name subsea, or submarine. However, such cables can be used beneath fresh water also, e.g. like they do to connect the mainland with the islands in the St. Lawrence River in US. The installation of such cables is a hard, tedious and super expensive work and, if necessary, they can be buried as deep, as the mountain Everest is tall.
5# Old style Zippo lighter
Credits: Townshend445 – The iconic American brand Zippo has been around since 1933 and due to the quality of its windproof lighters, it is no wonder why they are still so wildly popular all across the globe. The inventor of the lighter – George Blaisdell – was smoking a cigarette on the porch of the Bradford Country Club back in 1932. He noticed a man using a strange lighter from Austria, which had a protective top. George asked the man why he used such a clunky lighter, to which the man replied: “Well, it works.” George then decided to make his own version of the lighter and he called it Zippo, simply because he liked the way word ‘zipper’ sounds. The first Zippo models were sold in 1933 for $1.95 (a little over $35 in today’s money).
6# CT Scanner
Credits: Chap82 – The scan itself is know as computed tomography scan (formerly referred to as computerized axial tomography scan or CAT scan). It allows the user to see inside the object scanned without doing any actual cutting. The scanner makes use of computer-processed combinations of many X-ray measurements that are taken from different angles – thus, cross-sectional or tomographic images of the scanned object are produced.
7# Bowling Ball
Inside the ball, you can see an oddly shaped structure, which is called a weight block. It gives the ball the momentum it needs to roll down the lane properly. However, not all manufacturers make the same cores, therefore some are light bulb-shaped, while others are elliptical, and some are even a combination of both.
8# Military tank
Credits: RaymondPowellIII – Most of us are familiar with the concept of the military tank – however, it is not widely known that the polite Brits were the ones who introduced it during World War I. By early 1916s the prototype of the future tank was introduced. The heavily armored vehicle was used in combat for the first time in the Battle of Flers-Courcelette on 15 September 1916.
9# Wasp Nest
Credits: sverdrupian – It is commonly believed that the wasps are not the friendliest animals out there – but in fact wasps are rarely aggressive unless provoked. There are also a lot – a whole lot – of them, as they live in every corner of the world, except for the icy Antarctica. These buzzers make their papery nests from tree bark. They strip it from certain trees, chew it all up, add certain enzymes and regurgitate it in a pulp form to create their magnificent-looking nests.
10# Section of Golden Gate bridge cable
Credits: jaykirsch – The Golden Gate Bridge has two main cables. Each cable is composed of an overwhelming amount of 27,572 wires which are bundled into 61 strands. It is not that easy to wrap your head around this fact, but if the wires were one continuous length, they could wrap around the earth over three times.
11# Firework Shell
Credits: Dannythegirl – While we all know that the Chinese had invented fireworks, it seems as if Italians don’t get enough credit for the fact that they were the ones who actually introduced colorful fireworks. Not only that, but the Italian pyrotechnicians have also developed aerial shells back in the 1830s. As far as the modern fireworks are concerned, the inner anatomy of the aerial shell is the one responsible for the produced firework shape.
12# Hedgehog
This tiny and incredibly cute creature has somewhere between 5000 and 7000 quills. Muscles along the animal’s back can raise and lower them as a response to threatening situations. The inside of the quills is mostly hollow, with a series of complex air chambers making them light but strong.
13# ‘Lasagna’ style bulb planting
Credits: commoninja352 – This type of planting is also called double-decker bulb planting and it refers to the placement of bulbs within the container. Different bulbs bloom at different points of time, and by planting them all in the same container, the planter is guaranteed to have a whole spring’s worth of successive blossoming.
14# Tree Fern
Credits: Joe Lipson – It is believed that ferns are some of the oldest plants in the world, and a staggering number of 10,560 species of fern are known at the moment. These plants are members of the vascular plants group that reproduce via spores. Tree ferns can grow big – up to 25 meters (or 82ft) in height. One of the more interesting facts about ferns is that people during the Victorian times were absolutely obsessed with them. These plants appeared in pottery, wood, metal, textiles, printed paper, and sculptures and the obsession has even got its name – a Fern-Fever or Pteridomania.
15# Rock in New Zealand
Credits: pitcher654 – The rock, called Tokangawhā or Split Apple Rock, is located in a Tasman Bay off the northern coast of the South Island of New Zealand. The fracture of the rock (in geology, it is called joint) has formed naturally – such joints are common in granite and occur due to the exposure to rain and waves. However, the traditional Maori mythology says that the fracture occurred when two gods broke the rock apart.
16# Simulation to what happens when a small space debris object hits a spacecraft
Credits: Cropitekus – The photograph shows the results of a lab test impact between a small sphere of aluminum traveling at approximately 6.8 km per second (approximately 4.2 miles per second) and a block of aluminum 18 cm (around 7 inches) thick. The diameter of the impact crater is 9cm (3.5 inches), while the depth is 5.3 cm (around 2 inches).
17# Poppy Capsule
Credits: RyanSmith – The cross-sectioned capsule of a poppy may look pretty for some, while for others it may cause an irrational fear just by looking at it (the image is a perfect way to check whether you have trypophobia). Poppies are herbaceous flowering plants, known not only for their looks but for the drug-producing abilities, as well. Just recently, some rascal parrots have made the headlines, for they have been reportedly rampaging through the poppy farms in India, sometimes making 40 visits a day. The farmers believe that the birds might have become addicted to opium and are flying to farms frequently to get their daily fix of the drug.
18# Tortoise Skeleton
Credits: fubbleskag – Tortoises as well as turtles are in fact the only reptiles with hard and bony shells. To no surprise, the shell works as a protective armor from the harm of the environment. The outer layer – carapace – is the shell that we see on the animal and beneath it hides the inner bony layer, then followed (looking down) by the rib bones. The lower shell of the tortoise is called the plastron. If you ever were wondering why these lovely animals walk so slow – try imagining walking around yourself with heavy protective armor, as it most certainly weighs the animal down.
19# ‘Mark Twain Tree’ sequoia section with historical notations from year 550 to 1891
Credits: jaykirsch – The first documented sighting of the giant sequoia took place in the spring of 1852, when a hunter named Augustus T. Dowd, entered North Grove woods while chasing down a bear. The trees gained a lot of popularity and a lot of people came forward who wanted to make money out of these wonders of nature. In 1891 the giant “Mark Twain Tree” was cut down. A slice of its trunk was sent to the American Museum of Natural History in New York, and another slice to the British Museum of Natural History in Kensington, London.
20# Adding Machine
Credits: crystalandrockyfinds – An essential part of almost every office up until the 1970s, an adding machine is a class of mechanical calculators and was usually used for bookkeeping calculations. As the 70s approached calculators became more widely used and by the early 90s, personal computers took over. Thus, the adding machines were phased out and left most American offices completely by the year 2000.
21# Rattle Snake Rattle
Credits: sverdrupian – Native to North and South America, rattlesnakes are large venomous snakes, that are experts at hissing as well as their bone-chilling rattle. The rattle itself is hollow and is made of keratin (just like human’s fingernails) that is located at the end of the serpent’s tail. When the rattlesnake erects its tail and vibrates its muscles, these segments collide with each other, thus producing the rattling sound.
