Building an underground city 101 🕳️ If you dig a hole in the ground to hide from invaders, you have an underground city. Could you live 18 floors underground? 👇 How Turkey's ancient underground cities like Derinkuyu were built: rolling stone doors that only open from inside, air shafts, hidden wells, animals on the top floor, 18 floors deep for 20,000 people, a tunnel to the next city 8 km away, and the 1963 basement wall that revealed it. #undergroundcity #derinkuyu #turkey #ancienthistory #History #notsoboring

Building a canal 101 ⛵ If you dig a ditch from the river to your farm, you have a canal. Would you ride a boat up a hill? 👇 How canals and locks work: digging a canal wide enough for a boat, locks that lift boats uphill like a rubber duck in a bath, Leonardo da Vinci's lock gates that the water pushes shut, horses on the towpath, lock flights, and Scotland's Falkirk Wheel boat lift. #canal #locks #engineering #History #howitworks #notsoboring

The first zoo 101 🦁 If you put a fence around a lion, you have a zoo. Would you walk past a lion with no bars in the way? 👇 How zoos evolved: the Tower of London where English kings kept lions, an elephant and a polar bear that fished in the River Thames on a long chain, iron-barred cages after 1835, and the hidden-ditch enclosures invented in Germany in 1907 that most zoos still use today. #zoo #lion #toweroflondon #History #historyfacts #notsoboring

The first fire brigade 101 🚒 If you throw a bucket of water on a burning house, you have a fire brigade. Would you pay Crassus to save your house? 🔥👇 How firefighting evolved: bucket brigades, Crassus's Roman fire brigade that bought burning houses cheap, horse-drawn pumps with leather hoses, Dalmatians running in front, wooden water pipes and why hydrants are called fire plugs, and why firefighters slide down a pole. #firebrigade #firefighter #dalmatian #History #historyfacts #notsoboring

Building a treehouse 101 🌳 If you climb a tree to get away from a bear, you have a treehouse. Could you live 45 metres up a tree? 👇 How a real treehouse is built: a platform lashed with vines and palm bark, a leaf roof and walls, a fireplace up a tree, extra poles so it stops swaying, a notched-log ladder you pull up at night, and the Korowai of Papua who live 8 to 12 metres up, some as high as 45. #treehouse #korowai #papua #howitsmade #History #notsoboring

The first fridge 101 🧊 If you dig a hole in the ground and fill it with snow, you have a fridge. Would you trust ice that's been stored in a mud dome all summer? 👇 How ancient Persians kept ice in the desert 2,400 years ago: the yakhchal, a giant mud dome with walls 2 metres thick made with egg whites and goat hair, a hole on top to let hot air out, shaded ponds that froze on winter nights, and ice stored all summer for a whole city. #fridge #yakhchal #persia #ancienthistory #engineering #notsoboring

Building a swimming pool 101 🏊 If you dig a hole in your garden and fill it with water, you have a swimming pool. Guess what that pool smell really is 👇 How swimming pools evolved: the brick-lined Great Bath from 4,500 years ago, Roman pools heated by fire under the floor, drains and sand filters, chlorine, the deep end and diving board, lifeguards, and what that pool smell really comes from. #swimmingpool #pool #romans #History #howitsmade #notsoboring

The penny that saved Big Ben 🕰️ The most famous clock on Earth was running slow, and the experts couldn't fix it. Would you trust one penny with Big Ben? 👇 How Big Ben's Great Clock is kept on time: why the giant clock in London ran six seconds slow, the engineers who checked the gears, the air pressure, the temperature and even the pigeons, the 4-metre pendulum swinging inside the tower, and the old caretaker's strange idea to fix it with a penny. #bigben #london #clock #History #engineering #notsoboring

Building a ship 101 🚢 If you sit on a log in the water, you have a boat. Viking longship or Titanic: which one are you boarding? 👇 How ships evolved from a floating log: the 10,000-year-old dugout canoe, Viking longships with a keel, galleons full of cannons, the Vasa that sank 20 minutes into its first trip in 1628, iron hulls with watertight rooms, why the Titanic sank, and today's double-hulled giant ships longer than the Eiffel Tower is tall. #ship #titanic #vikings #History #howitsmade #notsoboring

Building a sea wall 101 🌊 If you pile up wet sand on a beach, you have a sandcastle. Would you live below sea level? 👇 How sea walls and dikes work: from a sandcastle and a moat to a packed sand wall with a clay skin and rock armour, the Dutch dikes that keep a quarter of the Netherlands dry below sea level, and the myth of the little Dutch boy who plugged a leak with his finger. #seawall #netherlands #dike #engineering #History #notsoboring

Building a bank vault 101 🏦 If you bury your gold in the garden, you have a bank vault. How would you break in? Wrong answers only 👇 How bank vaults evolved: from buried gold to iron safes, stone strongrooms, combination dials, giant round steel doors balanced to swing shut with one finger, time locks from 1874, and the New York gold vault behind a 90-tonne steel cylinder. #bankvault #bank #History #howitsmade #engineering #notsoboring

The first toilet 🚽 If you dig a hole and squat over it, you have a toilet. Would you have used the Romans' shared sponge? 🧽👇 How toilets evolved from a hole in the ground: Roman public toilets with one shared sponge on a stick, chamber pots thrown out of windows, the 1596 flushing toilet made for the Queen of England, the S-bend that stops the smell, and London's Great Stink of 1858 that led to the brick sewers we still use. #toilet #History #romans #howitsmade #historyfacts #notsoboring
