Nail polish was used to represent class in Ancient Egypt. The lower classes wore naked or light colours, while the upper classes favoured red hues (naturally). Cleopatra's tips were dyed a rusty colour with henna plant juice, while Nefertiti's were painted ruby colours.

The demise of massive stars results in black holes because the gravity of the star overwhelms the natural pressure that the star maintains to sustain its form. When the pressure from nuclear reactions drops, gravity overwhelms and destroys the star's core, and the star's various layers are hurled off into space, resulting in a supernova. The rest of the core collapses, leaving a place overrun by density and devoid of volume — a black hole.

Chances are good that you've heard of the Starbucks "secret menu," which is basically a huge list of drink combinations that aren't on the menu. Going through all of those options would take a very long time because as Starbucks spokesperson Lisa Passe told The Wall Street Journal, "If you take all of our core beverages, multiply them by the modifiers and the customization options, you get more than 87,000 combinations."

The Bailey Bridge, which spans the flowing Dras and Suru rivers, is the world's tallest. It was designed by the military to help them move fast through rivers during battle. A hydro-electric dam can be found to the left of the bridge, and a lake can be found to the right.

Wearing moonstone is thought to work as a talisman for travellers, allowing them to have a safe voyage without any losses or mishaps.

Just like Venice, Bangkok is also a city built on dozens of canals and with buildings standing on stilts. Although most of these canals have now been paved in, the nickname has stuck. However, another, less-cheerful point of similarity is the sinking of Bangkok. Due to rising sea levels and extensive development, Bangkok is sinking at a rate of 2 - 2.5 cm per year. Parts of Bangkok could be submerged in a few decades, so you might want to prepone your vacation there.

 

The pencil was a favourite of John Steinbeck and Ernest Hemingway. Hemingway wrote letters on a typewriter but did his serious work with a pencil.

In an interview with The Guardian, Teletubbies co-creator Anne Wood explained that the show's adorable and fluffy rabbits are not your typical pet bunnies. "They have to be enormous to match the scale," Wood explained. There was also an issue with their health. "The only ones we could discover that were acceptable had been bred on the continent to be eaten," Wood explained. "We provided them wonderful circumstances, ranging free across the Teletubby grasslands, but their breeding had given them enlarged hearts, and the animal trainer would greet me in grief practically weekly, telling me another had died."

The World's Most Famous Treasury Is Actually A Graveyard Petra's Treasury, contrary to popular belief, is not a looming maze of booby-trapped rooms designed to separate the righteous from the unworthy, but rather a relatively small area that is most likely a beautifully decorated graveyard. Any buried treasure was most likely removed a long time ago, but the Treasury facade is a work of art, lovingly carved by the Nabataeans centuries ago.

Several famous couples have won Oscars, but only one Hollywood family can claim to be truly Oscar-winning - The Minelli's. Liza Minelli, daughter of Vincente Minnelli (who won Best Director in 1959 for Gigi) and Judy Garland (who received a miniature Juvenile Award in 1940), won Best Actress for Cabaret in 1973.

Mount Sinai is the mountain that Moses climbed to receive the 10 commandments. Located in the Sinai Peninsula, this mountain is sacred in both Christian and Islamic religions. It is an important pilgrimage site and stands at 2,285 meters ( 7,497 feet) high. It is here you’ll find the UNESCO World Heritage Listed Saint Catherine Monastery that we mentioned above. 

The Main Belt's objects occasionally exhibit cometary activity and grow tails. Scientists speculate that this may be because they include water ice. Additionally, some of these bodies may be "degenerate" comets, which are comets that have nearly entirely lost their volatile material and are now barely distinguishable from typical asteroids.

Taste receptor cells in the pancreas enable it to detect the presence of sugar. Artificial sweeteners are also "tasted" by it. But unlike our tongue's taste buds, it doesn't send these sensations back to the brain. Instead, the pancreas uses this sensory data to maintain a healthy hormonal balance and blood glucose levels.

That's enough pencils to circle the globe 62 times, believe it or not.

Tulsi has a significant impact on the treatment and prevention of cardiovascular illnesses due to its decreased blood cholesterol content, suppression of ischemia and stroke, reduction of hypertension, and increased antioxidant qualities.

Brakes that do not lock up under full pedal pressure are becoming commonplace. They've saved numerous lives by letting the driver to keep steering the car and, hopefully, avoid a collision while braking hard. Mercedes-Benz improved the technology with Bosch in the 1970s before incorporating it into the S-Class in 1978. Anti-lock brakes were soon made standard on all Mercedes-Benz models.

Its origins are in the Greek words kalos, eidos, and skopios, which translate to "beautiful shape."

Mosquitoes are one of the most dangerous animals on the planet, yet their optimal life span may surprise you. The average lifespan is a little less than two months: a male mosquito normally survives for three to five days after mating, whereas a female mosquito can live for a month or two under optimal conditions. Females lay eggs every three weeks at the period.

Around 1904, a little child called Robert Eugene Otto, sometimes known as "Gene," had a strange-looking boy doll named Robert. Robert the Doll is supposed to be haunted, aware of his surroundings, and even responsible for a number of violent catastrophes. The film Child's Play was based on Robert's storey.

Moisturizing isn't only for the day! After cleaning your face at night, apply moisturizer since it works better on your skin when sleeping and is not exposed to the elements.

This is maybe the most stunning and perplexing anime truth mentioned here. In 1973, a manga called The Miraculous Notebook, also known as Fushigi na Techou, was produced. It told the story of a middle-aged worker who discovers a note that may murder people if their name is put on it. In 2003, the Death Note manga was launched. Is this just a coincidence? Could it be that the author of Death Note was aware of Fushigi na Techou?

The effects of toxic air are worse for those who are most at risk. The development of a child's lungs is harmed by air pollution. Additionally, it exacerbates pre-existing respiratory and cardiovascular diseases, especially in elderly patients. Because they frequently reside close to major roads, where air pollution is severe, the poorest members of our society suffer more than others. Air pollution has an impact on every motorist. However, especially when using side routes, pedestrians and cyclists are frequently subject to less air pollution than those who travel by car.

a protein that aids in the improvement of skin elasticity It tightens your skin while preventing sagging. Furthermore, elastin heals skin tissues and aids in cell renewal, revitalising your skin and making it youthful and wrinkle-free.

It required a lot of creativity to get the stones to stand up straight. The builders eventually chose a technique associated with woodworking rather than brickwork. They used tongue and groove joints to slot the stones together, creating mortice holes and protruding tenons. Timber poles were placed at the back of the pit as a brace support when the hole for the stones was dug. The stone was then placed into place and lifted up with ropes while rubble was stuffed into the pit to keep it in place.
