The Statue of Liberty’s color

Image: Pierre Blaché

We start our list with a moderately well-known fact: the Statue of Liberty’s beautiful emerald color is not original. Technically, it’s a sign of damage. While the statue's infrastructure is made of iron, its exterior is copper, which has turned green over time due to oxidation .

Fortunately, that same green coating now protects the statue from further damage and deterioration.

As strange as it sounds, this statement is true in a sense. The complex system of pumps and gates that administer the water of the Falls can be controlled by a central command.

In fact, part of Niagara Falls is even scheduled to be "turned off" in the coming years to replace some obsolete structures—just like a faucet.

We'll always love Julie Andrews for bringing the magical Mary Poppins to life in the 1964 Disney classic. Believe it or not, that was her very first film, and it earned her an Academy Award for Best Actress! Just a year later, she captivated audiences again in The Sound of Music , but Mary Poppins remains the role most closely tied to her charming persona.

Al Pacino first appeared as Michael Corleone in The Godfather (1972) and returned for the sequels in 1974 and 1990. His powerful performance turned Michael into one of the most iconic characters in film history. To this day, it's almost impossible not to think of Pacino as the unforgettable and complex successor to Don Corleone.

5

Marlon Brando – Don Vito Corleone

Image: Maximilian Kopsch

When it comes to exceptional characters, we can't leave out Don Vito Corleone, brought to life by the legendary Marlon Brando in The Godfather (1972). This role was so iconic that it redefined the image of the gangster on screen. When we picture Brando, we often imagine him wearing the prosthetics he used to portray the mob boss. The performance earned him an Academy Award for Best Actor, which he famously declined in protest of Hollywood's treatment of Native Americans.

If there's one thing our generation knows well, it's that "life is like a box of chocolates." That memorable line comes from Forrest Gump , played by Tom Hanks in 1994. With his big heart, kindness, and unexpected wisdom, Forrest won over audiences everywhere. The impact of the character was so powerful that it not only cemented Hanks’ status as a leading actor but also forever linked his image to the role.

Harrison Ford – Indiana Jones

Image: Intricate Explorer

If there's one actor forever tied to Indiana Jones , it’s Harrison Ford. He first took on the role in Raiders of the Lost Ark (1981), and then embodied the archaeologist again in sequels released in 1984, 1989, 2008, and 2023. With his iconic fedora and whip, Ford made the character unforgettable, so much so that it's hard to imagine anyone else bringing him to life.

10

Sylvester Stallone – Rocky Balboa

Image: Luisa Frassier

Although some producers wanted to cast another actor, Sylvester Stallone refused to let anyone else bring the story of Rocky Balboa to the screen. As we know, Stallone wrote the script with the intention of playing the role himself, and thank goodness he did! It's hard to imagine anyone else portraying the iconic boxer the way he did. And we're not the only ones who think so; the Academy clearly agreed, as Rocky (1976) earned ten Oscar nominations.

Beehives

Image: Meggyn Pomerleau

The first entry on the list goes to perhaps the most famous and finest example of animal architecture: the beehive. Built by incredibly industrious insects, beehives are among the most efficient structures in nature .

The regular hexagons provide the least-perimeter way to enclose infinitely many unit areas in the plane: the best way to separate the surface of their hives in equal parts all around, using the least possible total perimeter, thus reaching 100% efficiency in design.

2

Ant colony

If beehives aren’t the first thing that comes to mind when thinking about animal architecture, there’s a good chance you’re thinking of ant colonies.

Ants build the elaborate colony structure by hollowing out the area with their mandibles, grain by grain, without a blueprint, without a leader, and in total darkness . Unless the soil dries out dramatically, the chambers will keep their form.

Prairie dog town

Image: Moritz Kindler

These cute creatures excavate their homes by digging burrows into the ground, primarily in the Great Plains of North America. The region experiences extreme seasonal weather variations from season to season, requiring their homes to be built to withstand extreme temperatures, floods, and fires.

These underground "towns" have nursery rooms, pantries, living quarters, and temporary refuges —each smartly separated to serve a specific purpose.

4

Beaver dam

Image: Derek Otway

Another famous animal architect, the beaver, uses felled trees to build dams . These dams create still ponds where beavers can construct their winter homes, called lodges.

These creatures prepare for winter by covering their lodge with a fresh coat of mud, which hardens to create a barrier against the cold and predators.

5

Caddisfly larvae case

Octopus den

Image: Serena Repice Lentini

It’s no secret that octopuses are incredibly intelligent animals, and their dens are proof of it. These clever mollusks use shells, stones, and even discarded human objects to reinforce their homes . Some species go a step further, decorating their dens with seaweed and other found materials.

7

Bagworm silk tent

Image: Maëva Vigier

Bagworms construct silk tents around themselves using bits of leaves, twigs, and other debris . These tents serve as mobile homes, providing protection as the insect feeds and grows.

Some species even camouflage their bags to blend into the environment, helping them avoid predators.

Coral reefs are massive structures built by tiny coral polyps. These marine architects secrete calcium carbonate to form hard skeletons, gradually creating vast and complex habitats for a myriad of marine species. They are often referred to as the "rainforests of the sea" due to their biodiversity.

10

Spider web

Image: freestocks

Another famous architect from the animal kingdom, the spider, creates webs that serve as both homes and hunting tools . The silk used in these webs is incredibly strong, and different species produce a variety of designs, including sheets, orbs, and funnel shapes.

11

Swallow nest

Image: Tobias Arweiler

Swallows build cup-shaped nests that can house entire colonies , using mud pellets, usually attached to vertical surfaces like cliffs or man-made structures.

The construction is precise and stable, providing protection for their young against predators and environmental elements.
