For all the television shows that set out to solve the world’s great mysteries, and the intrepid adventurers hunting for lost artifacts, some of the most famous treasures of history are still missing. These include one of the most dazzling rooms ever made, a giant yellow diamond, and the work of a renowned Greek poetess. Here are just a few of these enigmas.

1. THE AMBER ROOM

Designed in the 18th century by German sculptor Andreas Schlüter and Danish amber artist Gottfried Wolfram, and gifted to Russia in 1716, the Amber Room of Catherine Palace was the pride of the Saint Petersburg area. Lavishly decorated in jewels, gilding, and, of course, panels of amber, it was sometimes called the "Eighth Wonder of the World."

When the German army neared Saint Petersburg during World War II, the curators at Catherine Palace knew they had to hide this treasure. They tried to take it apart, but the dry amber crumbled in their hands; instead they hid it behind wallpaper. German soldiers found the Amber Room anyway, and broke it down into pieces that were packed in crates and shipped to Königsberg, then part of Germany (now part of Russia). For a time, the Amber Room was installed in the Königsberg castle museum. After that, its fate gets fuzzy. Some researchers believe it was destroyed in the bombardments of the war, while others think that it’s still hidden somewhere. Despite periodic claims of it being found—and verified remnants turning up in 1997—most of it remains missing. In 2003, a reconstruction of the Amber Room was unveiled near Saint Petersburg, so visitors can at least get a glimpse of its lost glory.

2. SAPPHO'S POEMS

Ancient sources state that the Greek poet Sappho penned nine volumes of writing, but only a couple of full poems—and a few hundred lines on shreds of papyrus and potsherds—survive. Some contain just a handful of words, yet they hint at the passion in her work: "I desire/And I crave," one remnant reads. Many of these bits survive thanks to her popularity in antiquity, since her writing was frequently quoted in other sources.

There may be more of Sappho's work to discover. A late 19th- to early 20th-century excavation at a trash dump in Oxyrhynchus, Egypt, turned up valuable fragments of her poems. As recently as 2014, two works on papyrus fragments were identified by an Oxford papyrologist. With any luck, there may still be scattered remains of her poems to unearth in the detritus of the classical world.

3. THE FLORENTINE DIAMOND

According to legend, Charles the Bold—the Duke of Burgundy—carried this 132.27-carat yellow diamond into the 1477 Battle of Nancy as a talisman. The treasure did little to protect him, however, and he fell along with his gem. His mutilated corpse is said to have later been recovered from the battlefield, but the diamond was gone, supposedly picked up by a scavenger who sold it for two francs because he thought it was just glass.

However, in the 1920s the art historian Nello Tarchiani did archival research that revealed the diamond likely had no connection to the duke. The gemstone had originated in southern India, where it stayed until the Portuguese seized the area in the 1500s. Soon afterward, it made its way to Europe and into the hands of a series of illustrious owners, including Ferdinand de’ Medici, the Duke of Tuscany, in 1601. It was in the treasury of the Medicis in Florence that it got its name—the Florentine Diamond—and most likely its glistening, 126-facet double rose cut.

When Anna Maria Luisa de' Medici, the last of the Medici ruling family, died in 1743, the diamond didn't stay with the treasure trove she bequeathed to the Tuscan state. Instead, Francis Stephan of Lorraine (who later became the Grand Duke of Tuscany and Holy Roman Emperor) bought it for his wife, Empress Maria Teresa, herself at the end of the House of Habsburg line. For a time, the Florentine diamond became part of the crown jewels in Vienna. Then the Austro-Hungarian Empire collapsed after World War I, and the diamond, it’s believed, was carried into exile in Switzerland by its last emperor, Charles I.

But where is it now? There are many theories on its disappearance, including that it was sold by the exiled emperor, and perhaps cut into smaller gems for that purpose. Others posit that it was stolen and spirited to South America. With no trace of the diamond in years, its whereabouts remain a mystery.

4. FABERGÉ EGGS

The legendary House of Fabergé was once the largest jeweler in Russia, employing 500 designers and craftsmen to transform everything from mantel clocks to cigarette cases into delicate and elaborate works of art. Their most famous achievement is the series of jewel-drenched Easter eggs they produced for Czars Alexander III and Nicholas II, which the Russian rulers gave as gifts to their wives and mothers. Each egg contained a surprise, from the Trans-Siberian Railway Egg (with a wind-up train made from gold and platinum) to the Bay Tree Egg (shaped like a tree, with a mechanical singing bird emerging from its branches). After the Russian Revolution overthrew the Romanov Dynasty—and the imperial family was executed—the new Soviet rulers seized the eggs. Lenin was interested in preserving such cultural heritage, but Stalin saw them as economic resources, and the eggs were sold off. Out of the 50 Imperial Eggs (as the eggs created for the czars are known), seven are missing.

Information on the lost eggs is sparse. There are few photographs—the only image we have of one of the eggs, the Cherub with Chariot Egg, is a reflection in the glass of a display case. Sometimes the surprises inside are detailed in records, and in other cases they remain a mystery. However, in 2012 a Midwest man who had bought what he thought was a fancy doodad for scrap gold happened to do an internet search on the name on the little clock inside: “Vacheron Constantin.” He discovered that his trinket, which he’d bought for $14,000, was one of the lost Imperial Eggs, worth $33 million.

5. CROWN JEWELS OF IRELAND

On July 6, 1907, regalia belonging to the Grand Master of the Order of St. Patrick—referred to as the "Crown Jewels of Ireland"—were discovered to be missing, the keys boldly left hanging in the safe’s lock. The pricey pieces, which included a diamond star and badge, had been presented to the order of knights in 1830. As added insult, five collars of Knight Members of the Order had also been spirited away.

Security was perhaps a bit lax. A safe room had been built for Dublin Castle in 1903, yet the safe that protected the jewels was too big to fit in the door, so it was kept in a library strongroom.

An investigation was immediately launched, but a century later, the case is unsolved. One rumor is that the investigation was halted under the orders of Edward VII because it ended up touching on a sexual scandal at Dublin Castle. One top suspect is Francis Shackleton, second-in-command at the castle, and brother to the famed explorer Ernest Shackleton; some say he may have been trying to raise funds for his brother's polar expedition.

6. ART FROM THE ISABELLA STEWART GARDNER MUSEUM

In the early morning of March 18, 1990, the security guards at the Isabella Stewart Gardner Museum in Boston buzzed in two men claiming to be police officers. Once inside, they handcuffed the guards and revealed their true intention: stealing art. They made off with 13 works valued at $500 million, the biggest unsolved art theft in the world.

Vermeer, Rembrandt, Degas, and Manet works are among the stolen art, although strangely, the robbers also opted to take a bronze eagle from the top of a Napoleonic flag and an ancient Chinese beaker rather than other, more valuable objects nearby. Because the museum’s collection and layout are permanent—both the legacy of the late art collector Isabella Stewart Gardner—the frames of the missing artworks are kept empty, a memorial and a reminder that the burglars are still at large. The FBI believes the paintings made their way to organized crime circles in Philadelphia, but haven’t had a lead since 2003. Currently, the reward is $10 million for information leading to the artworks’ recovery.

7. THE HONJŌ MASAMUNE

At the end of World War II, citizens in Japan were required to turn over privately owned weapons, including historic pieces. Among them was one of the most famous swords ever made: the Kamakura-period Honjō Masamune. Created by Masamune, who lived circa 1260-1340 and is often considered Japan’s greatest sword maker, the sword was celebrated for its strength and artistry.

Its last owner was Tokugawa Iemasa, who brought the Honjō Masamune, along with other heirloom swords, to a Tokyo police station in compliance with the Allied orders. They were handed off to someone in the Foreign Liquidations Commission of AFWESPAC (Army Forces, Western Pacific), then disappeared. Some surrendered swords from this era were brought back to the United States by American soldiers, while others were melted or tossed in the sea. Today, the fate of the Honjō Masamune is unknown.

Now more than ever, it’s important to have a good hobby. Of course, a lot of people—maybe even you—have been obsessed with learning TikTok dances and baking sourdough bread for the last few months, but those hobbies can wear out their welcome pretty fast. So if you or someone you love is looking for something that’s a little more intellectually stimulating, you need to check out the Flybrix LEGO drone kit from Fat Brain Toys.

What is a Flybrix LEGO Drone Kit?

The Flybrix drone kit lets you build your own drones out of LEGO bricks and fly them around your house using your smartphone as a remote control (via Bluetooth). The kit itself comes with absolutely everything you need to start flying almost immediately, including a bag of 56-plus LEGO bricks, a LEGO figure pilot, eight quick-connect motors, eight propellers, a propeller wrench, a pre-programmed Flybrix flight board PCB, a USB data cord, a LiPo battery, and a USB LiPo battery charger. All you’ll have to do is download the Flybrix Configuration Software, the Bluetooth Flight Control App, and access online instructions and tutorials.

Experiment with your own designs.

The Flybrix LEGO drone kit is specifically designed to promote exploration and experimentation. All the components are tough and can totally withstand a few crash landings, so you can build and rebuild your own drones until you come up with the perfect design. Then you can do it all again. Try different motor arrangements, add your own LEGO bricks, experiment with different shapes—this kit is a wannabe engineer’s dream.

For the more advanced STEM learners out there, Flybrix lets you experiment with coding and block-based coding. It uses an arduino-based hackable circuit board, and the Flybrix app has advanced features that let you try your hand at software design.

Who is the Flybrix LEGO Drone Kit for?

Flybrix is a really fun way to introduce a number of core STEM concepts, which makes it ideal for kids—and technically, that’s who it was designed for. But because engineering and coding can get a little complicated, the recommended age for independent experimentation is 13 and up. However, kids younger than 13 can certainly work on Flybrix drones with the help of their parents. In fact, it actually makes a fantastic family hobby.

17 Odd Things We've Sent to Space for Some Reason

There's a Starman waiting in the sky.
There's a Starman waiting in the sky.

Artifacts, personal and pop cultural totems, and even the dead have made the journey from our planet to the outer reaches of the heavens. We've covered some odd items that have gone to space before; here are 16 more unusual things that took a trip to the cosmos.

1. Human remains

Thanks to Celestis, a company that specializes in booking “memorial spaceflights,” and an agreement with private rocket company SpaceX, the remains of several people who have died have been launched into the great beyond (for a couple of hours, at least). Star Trek creator Gene Roddenberry's remains were on the inaugural Celestis flight in 1997; his remains took flight again in 2012 with the remains of actor James Doohan, who played Scotty. Astronaut Gordon Cooper’s ashes were also on that flight.

2. A toy dinosaur

In 2020, astronauts aboard SpaceX’s first crewed missions packed an unusual travel companion: a plush dinosaur. During the historic flight, Bob Behnken and Doug Hurley were accompanied by “Tremor,” a sparkly Apatosaurus. The crews’ sons chose the toy, which acted as a zero-g indicator.

3. Actual dinosaurs

In 1985, astronaut Loren Acton brought small bits of bone and eggshell from the duck-billed dinosaur Maiasaura peeblesorum along on a mission on SpaceLab 2. Thirteen years later, the skull of a meat-eating Coelophysis from the Carnegie Museum of Natural History was a passenger on a trip to the Mir space station.

4. A car

In 2018, Elon Musk took off roading to a whole new level. SpaceX launched a red Tesla Roadster into space as part of the Falcon Heavy rocket’s test flight. “Starman,” a mannequin clad in a spacesuit, sits in the car’s driver’s seat. You can track Starman’s cosmic journey here.

5. Salmonella

Lots of strange things have been brought to space in the name of science—including salmonella. Two shuttle flights to the International Space Station (ISS) contained samples of salmonella to determine how the bacteria would react to low gravity, and the findings were kind of scary. When the salmonella returned to Earth after being in orbit for 12 days on the space shuttle Atlantis, the bacteria became even more virulent. In the first study to examine the effect of space flight on the virulence of a pathogen, the bacteria that had taken a space trip was three times as likely to kill the lab mice as the salmonella that was kept on Earth in as close to similar conditions as possible.

6. Tardigrades

Tardigrades, a.k.a. water bears, became the first animals to survive exposure in outer space. The eight-legged creatures typically spend their days on a moist piece of moss or enjoy feasting on bacteria or plant life at the bottom of a lake, but they survived being frozen at -328°F or heated to more than 300 degrees on their trip to space. The water bears, which typically don’t grow more than 1 millimeter in length, were dehydrated and exposed in space for 10 days by a group of European researchers. Back on Earth and rehydrated, 68 percent of the tardigrades that were shielded from the radiation survived. A handful with no radiation protection not only came back to life, but later produced viable offspring. Excitedly, an “amateur tardigrade enthusiast” theorized the water bears must be extraterrestrial in origin if they can handle such conditions, but that claim has boringly been denied by the Swedish and German scientists, who made up for it by naming their experiment "Tardigrades in space," or TARDIS.

7. Sperm

Without gravity, samples of animal sperm don’t work the way they should. Putting bull sperm in orbit made the tiny cells move faster than usual. Meanwhile, in sea urchin sperm that flew on NASA missions, the process of phosphorylation screeched to a halt when the enzyme known as protein phosphatase didn’t do its job. In 1979, two female rats that went to space became pregnant but didn't carry the fetuses to term, and the males’ testes shrank along with their sperm count. Fortunately (or unfortunately), one creature has been able to reproduce far from our planet: the cockroach.

8. See-through fish (medaka)

Since the medaka’s organs are clearly visible because of its transparent skin, this species of fish was the obvious choice for scientists to test the effects of microgravity on marine life—and to help determine why astronauts suffer from a decrease in bone density while in orbit. Bones naturally break down and rebuild, and osteoclasts help break down bones while they're under construction, as it were. In space, the process gets wonky, which is why astronauts endure two-hour high-intensity exercise routines and take vitamin D supplements. With the medaka’s help, scientists discovered the time-consuming space exercise could be avoided, and by finding the mechanism in bone metabolism, it may lead to the development of an osteoporosis treatment.

9. Soft drinks

In 1984, Coca Cola decided it wanted to put the first carbonated beverage on a space shuttle. The company spent $250,000 developing a can that would work without gravity, keep the drink fizzy, and not spill all over the place—even changing some of their formula in the process. After NASA agreed, Pepsi responded by saying it felt left out. NASA then announced that any soft drink manufacturer could participate if they created a viable container. In 1985, four cans of Pepsi and four cans of Coke were on board the Challenger; the day shifters drank Coke, and the night owls consumed the Pepsi. Neither of the sodas were to their liking.

10. Pizza

Pizza Hut wasn’t satisfied with simply being the first company to advertise on a rocket in the year 2000, so one year later it paid the Russian space agency about $1 million to become the first company to deliver a pizza to someone in space. The pizza delivered to cosmonaut Yuri Usachov included a crispy crust, pizza sauce, cheese, and salami (because pepperoni grows moldy over a certain period of time). Extra salt and spices were also added to compensate for the deadening of taste buds from space travel, and it was delivered in a vacuum seal. Usachov gave the pizza a thumbs up.

11. A cheese wheel

In 2010, SpaceX placed a wheel of Le Brouere cheese on an uncrewed spaceship to honor the classic Monty Python’s Flying Circus cheese shop sketch. To add to the pop culture celebration, SpaceX sealed the cheese wheel in a metal cylinder bearing the image of the film poster from the 1984 Val Kilmer movie Top Secret!. It was claimed to the first cheese to travel to orbit on a commercial spacecraft.

12. A corned beef sandwich

Astronaut John Young smuggled a corned beef sandwich on board the Gemini 3 in 1965. The following exchange was recorded:

Gus Grissom: What is it?
Young: Corn beef sandwich
Grissom: Where did that come from?
Young: I brought it with me. Let’s see how it tastes. Smells, doesn’t it?

The entire incident lasted 30 seconds, with the sandwich only being consumed for 10 of those seconds, before being put back away inside Young’s flight suit.

While legend has it that Yuri Gagarin was accompanied by a homemade salami sandwich in 1961, the Russians had a specialized vacuum kit so they could clean up after eating to prevent any clogging of shuttle equipment. The Americans were just supposed to consume food from tubes, so Young was putting himself somewhat at risk for the five-hour mission. The astronaut got a stern talking to; he later landed on the Moon during the Apollo 16 mission.

13. Guns

Unlike astronauts, Soviet cosmonauts went into space locked and loaded, carrying a triple barrel TP-82 capable of 40 gauge shotgun rounds. The heavy duty weapon was deemed necessary after 1965, when cosmonauts landed on Earth and became stranded in the Ural Mountains. The isolated cosmonauts feared the local wolves and bears would attack them. In 2006, the TP-82s were replaced with a standard semi-automatic.

14. Buzz Lightyear

A Buzz Lightyear toy spent 467 days in space, orbiting the Earth on the ISS before having a ticker-tape parade in Disney World’s Magic Kingdom thrown in his honor. The toy’s namesake, Buzz Aldrin, was a special guest.

15. Amelia Earhart’s watch

Amelia Earhart was the first president of an international organization of licensed women pilots called The Ninety-Nines. One member of that group is astronaut Shannon Walker, who in October 2009 was presented with a watch, owned by current group director Joan Kerwin, that Earhart wore during her two trans-Atlantic flights to bring onboard the ISS. Earhart, of course, was the first female trans-Atlantic passenger in 1928, and flew from Newfoundland to Northern Ireland solo on May 20, 1932. She gave her watch to H. Gordon Selfridge Jr., who passed it along to Ninety-Nines charter member Fay Gillis Wells. Kerwin acquired the watch at an auction.

16. A treadmill named after Stephen Colbert

Stephen Colbert, as he is wont to do, managed to crash an online contest. He garnered enough write-in votes and technically won the right to name a room at the space station after himself. Though NASA reserved their right to ignore write-in votes, the agency compromised by naming their second-ever model of treadmills after him, dubbing it the Combined Operational Load-Bearing External Resistance Treadmill, or COLBERT. The treadmill’s manufacturer nickel-plated the parts, and unlike a standard treadmill, there are elastic straps that fit around a runner’s shoulders and waist to keep them from careening across the space station. The announcement was made by astronaut Sunita Williams on an episode of The Colbert Report; Williams ran a marathon on the previous treadmill while living at the space station in 2007, jogging in place with the concurrent Boston Marathon.

17. An issue of Playboy Magazine

Some members of the backup crew of Apollo 12 included some Playboy spreads on the crew’s checklists, which were attached to Pete Conrad and Alan L. Bean’s wrists as they explored the lunar landscape. Astronaut Richard Gordon, who stayed in orbit around the Moon during the mission, also found a topless DeDe Lind calendar hidden in a locker, which was labeled “Map of a Heavenly Body.”
