A shock wave can be produced by sound. Sharp and repetitive sounds, such as drumming, can cause shock waves when an object vibrates at a high pace. A shock wave is produced by a loud bang or clap. While a shock wave caused by a clap is harmless, a shock wave caused by an explosion is deadly since it can kill many people.

According to the CDC, approximately 7% of children between the ages of 3 and 17 years old have been diagnosed with anxiety. Since children are still developing their verbal skills they can’t say, “I have anxiety” or “I’m really worried.”
Instead, their anxiety shows up in complaints such as stomach aches, headaches, or behavioral issues like temper tantrums. Other common anxiety symptoms in children include restlessness, inattention, avoidance, and frequent meltdowns. Sadly, these symptoms often get misdiagnosed as ADHD – and then medicated. 

People found this extremely frustrating because round pencils frequently rolled off surfaces. As a result, the popular hexagonal pencil shape was introduced. People used to use breadcrumbs to erase their mistakes before erasers were invented.

Obviously, it failed. McDonald's has been introducing healthy choices onto its menus for the last decade. It now provides a wide variety of salads, and in 2011, it made it possible to substitute apples for fries in Happy Meals. However, before settling on apples, the fast food company experimented with a variety of fruits and vegetables, most notably broccoli. But not just any broccoli will do. Recognizing that youngsters dislike the waxy green vegetable, McDonald's designed it to taste like bubblegum.

Australia and New Zealand have a long history of competition, but one Australian guy came very close to winning in 2006. In May 2006, he launched a bid on the New Zealand e-commerce platform. Bids began at $0.01. Bidding prices reached $3,000 when eBay administrators took it down, stating that "obviously, New Zealand is not for sale." Nonetheless, New Zealand was irritated by the hoax. At the time, the country's foreign minister referred to it as "nonsensical foolishness."

Harvard is an Ivy League school. These schools were first known to have highly competitive athletic teams. As the teams gained more funding, the universities improved their standards of education and as a result, these schools are now an elite group that produces distinguished graduates. Ironically, Harvard actually tried banning football twice because of its violent and dangerous characteristics. However, the pressure from alumni and students has helped keep Harvard’s football legacy intact. The first stadium was completed in 1903. Their biggest rival? Another Ivy – Yale!

Coca-Cola BlaK had a brief existence, lasting just from 2006 to 2008, and was only available in seven countries. Coca-Cola, on the other hand, has stated that it intends to release another coffee-related product in the future.

Billions (rather than millions)... MILLIONS of Call of Duty multiplayer battles have already been played long before Modern Warfare 3, Black Ops 2, or even the impending Ghosts. In total, 1.4 billion matches have been played, which is far more than all known battles in human history combined.

India is home to one of the world's hottest chillies, the bhut jolokia or ghost pepper, which is 400 times hotter than Tabasco sauce. The chilli, which is grown in the states of Arunachal Pradesh, Assam, Nagaland, and Manipur, was certified as the world's hottest in 2007 by Guinness World Records, but it fell out of that position in subsequent years.

Thyme needs to be kept out of heat, moisture, and sunshine in an airtight container. Make sure the spices stay cool; keep them away from any outside walls to prevent them from being exposed to the daylong, sweltering summer sun (even light can affect dried herbs).

The Nabataeans revered their dead and took special care to honor them as they transitioned from this world to the next. They constructed over 1,000 protected tombs in the mountains surrounding the city. These tombs coexist with depictions of their gods, creating a sense of fluidity between the sacred and the mundane.

Hematemesis, a sign of heavy abrupt bleeding, is characterized by feeling incredibly dizzy and vomiting blood.

As previously said, the average butterfly has a limited lifespan; even in their prime, these insects are among the most vulnerable. Staying living for as long as possible provides the butterfly with more chances to mate, and the survival of its species is critical. As a result, butterflies frequently utilize their wings as a form of defense. A butterfly's wings are frequently its best protection, either by folding to blend in with their surroundings or sporting a rainbow of colors and patterns to deter predators.

Libya imports the majority of the food it consumes due to its inability to produce it locally. Because the nation is located within the vast Sahara desert, it receives extremely little precipitation. It also has weak soil and a harsh climate, both of which hinder food production. The financing of the Great Manmade River Project, which was designed to irrigate farmed fields, was a major attempt by former Libyan President Gaddafi to reverse the situation. This project ended up becoming the largest irrigation project in the world. It consists of a 1750-mile subterranean water pipe network. Libya's people, meanwhile, continue to rely on imported food to survive.
