Breaking the sound barrier refers to exceeding the speed of sound, which is approximately 767 mph at sea level. While aircraft are commonly associated with breaking the sound barrier, other objects can also achieve this feat. For example, in 2012, Felix Baumgartner broke the sound barrier during a freefall jump from a balloon 24 miles above New Mexico. Interestingly, some people have claimed that snapping a towel can break the sound barrier, but this has been a subject of debate. While some experiments suggest that the tip of a snapped towel can exceed the speed of sound, creating a miniature sonic boom, others argue that the results may not be conclusive.

Snapping a towel can break the sound barrier
Breaking the sound barrier refers to exceeding the speed of sound, which is approximately 767 miles per hour at sea level. While it is commonly associated with aircraft, several other objects and occurrences can break this barrier. For example, in 2012, Felix Baumgartner broke the sound barrier during a freefall jump from a balloon over New Mexico.
Interestingly, snapping a towel can also surpass the speed of sound and break the sound barrier. This phenomenon has been the subject of various experiments and discussions. In one instance, a group of students from the North Carolina School of Science and Mathematics embarked on a project to prove that a snapped towel could break the sound barrier. Their efforts spanned several months, and they encountered numerous challenges along the way. Eventually, they succeeded in capturing proof that the end of the towel did, in fact, break the speed of sound.
The speed achieved by the tip of a snapped towel can be compared to that of a bullwhip, which is known to create a sonic boom when it exceeds the speed of sound. The cracking noise produced by a bullwhip is a miniature sonic boom, and a snapped towel can generate a similar sound. While the specific mechanics of this phenomenon are still being explored, it highlights the fascinating ways in which everyday objects can surpass the speed of sound.
It is worth noting that breaking the sound barrier in everyday scenarios, such as snapping a towel, does not produce the same dramatic effects as supersonic aircraft. However, it showcases the diverse range of objects and occurrences that can surpass the speed of sound, challenging our assumptions about the speed and power required to break the sound barrier.
In summary, snapping a towel can indeed break the sound barrier. This intriguing phenomenon has captured the curiosity of scientists and enthusiasts alike, leading to a deeper understanding of the diverse ways in which the speed of sound can be surpassed in our daily lives.

Bullwhips break the sound barrier
Whips, including bullwhips, can break the sound barrier. The cracking sound of a whip is produced when a section of the whip moves faster than the speed of sound, creating a small sonic boom. This phenomenon has been known for over a century, with Otto Lummer recognizing it as a sonic boom in 1905, and it was experimentally proven by Carrière in 1927 using high-speed shadow photography.
The cracking of a whip is the result of a loop traveling along the whip, gaining speed until it surpasses the speed of sound. This loop, rather than the tip of the whip, has been identified as the primary source of the sonic boom. The whip's design, with a long, tapered, and finely braided leather thong, enables the creation of this loop that accelerates to supersonic speeds.
Bullwhips, in particular, were designed to be carried in a saddle, and they require practice and dexterity to crack effectively. They are commonly used in whip-cracking competitions, which have gained popularity in Australia and the United Kingdom, showcasing complex routines and precise target work.
The act of whipcracking has evolved from its traditional use in livestock driving and horse riding into an art form. It has become a part of rodeo shows and competitive sports, with various types of whips employed, including bullwhips and Australian stockwhips. The skill and precision involved in cracking a bullwhip to break the sound barrier contribute to its appeal in these performances and competitions.

Felix Baumgartner broke the sound barrier in a freefall
On 14 October 2012, Austrian skydiver Felix Baumgartner became the first person to break the sound barrier in freefall. He jumped from a height of 38,969.4 metres (127,852 ft) and reached a maximum velocity of 833.9 mph (1,342 km/h). Baumgartner's feat was the result of five years of meticulous planning and a $20 million (£12.45 million) budget, funded by Red Bull. The project, known as Red Bull Stratos, was more than just a stunt; it was a scientific endeavour that provided invaluable data for researchers working on high-performance, high-altitude parachute systems.
During his descent, Baumgartner set several records, including the fastest speed of freefall at 1,357.6 km/h (843.6 mph), making him the first human to break the sound barrier outside a vehicle. He also broke records for exit altitude and vertical speed without a drogue. Baumgartner's jump exceeded the altitude for the highest ever manned balloon flight, reaching a height of 128,100 ft (39 km) above sea level.
The danger of the event was emphasised by the fact that the live broadcast had a built-in delay, sparing the public in case of a tragic outcome. Baumgartner himself acknowledged the risks, stating that once he was standing at the top of the world, his focus was solely on returning alive. Indeed, there was concern early in the dive when Baumgartner was seen tumbling, and his visor fogged up due to a malfunctioning heater. However, he was able to use his vast experience to correct his fall and resolve the fogging issue.
Baumgartner's achievement has had a significant impact on research into the stratosphere and space, as well as spacesuits and safety equipment. It also pushed the boundaries of online video, with Baumgartner and Red Bull breaking records for the most concurrent views for a live event on YouTube. Baumgartner's name was added to Vienna's Street of Champions, and he was nominated for several awards, including a World Sports Award and two categories in the NEA Extreme Sports Awards.

Google executive Alan Eustace broke the sound barrier
On October 24, 2014, Google executive Alan Eustace performed a parachute jump from the edge of space, breaking the sound barrier and setting several world records. Eustace ascended in a balloon to a height of 135,890 feet, and then pulled a detachment device on his spacesuit, beginning a 14-minute freefall back to Earth. During the jump, Eustace reached a top speed of 822 mph, surpassing the speed of sound and breaking the previous world record held by Felix Baumgartner.
Eustace's supersonic skydive was part of a project by Paragon Space Development Corp and its Stratospheric Explorer team. The team had been working secretly for years to develop a self-contained commercial spacesuit that would enable people to explore the upper reaches of the Earth's atmosphere, about 20 miles above the surface. The technology used in the balloon, spacesuit, and other systems from the jump will contribute to advancing commercial spaceflight and space tourism initiatives.
Interestingly, Eustace himself did not feel or hear anything when he broke the sound barrier. He noted that there was no noise during his acceleration because there was no air resistance. The absence of noise continued even after surpassing Mach 1.22. It was only when he started to decelerate that he could hear noise again. However, the ground crew did hear the resulting sonic boom, indicating that the sound barrier had been broken.
Eustace's achievement highlights the advancements in technology that make such feats possible. His strong belief in technology and extensive testing played a crucial role in the success of his jump. By breaking the sound barrier, Eustace has not only pushed the boundaries of exploration but has also contributed to the development of space exploration and tourism, making it safer and more accessible for future adventurers.

Dropping a rock into water can break the sound barrier
Breaking the sound barrier typically refers to the act of surpassing the speed of sound, which is approximately 767 miles per hour (mph) or 1,235 kilometres per hour (km/h) in air. The speed of sound in water is about five times greater, at around 3700 km/h or 2300 mph.
When an object travels faster than the speed of sound, it generates a sonic boom—a loud sound caused by a buildup of sound waves. The speed of sound varies depending on the medium through which the sound waves travel. For example, the speed of sound in water is faster than in air due to water's higher density.
It is theoretically possible to break the sound barrier in any medium, including water. However, the amount of energy required increases with the viscosity and speed of sound in the medium. In the case of water, the energy required is so immense that it would likely cause the surrounding water to vaporise instantly. Therefore, while it may be technically possible to break the sound barrier by dropping a rock into water, it is not feasible in practice.
It is worth noting that the speed of sound in a medium can be influenced by factors such as temperature. For instance, the speed of sound in water at 20 degrees Celsius is approximately 1482 metres per second.
Additionally, it is important to distinguish between breaking the sound barrier in a medium and breaking the sound barrier while submerged in that medium. For example, a torpedo can achieve Mach 1 (the speed of sound) in air while being launched from a submarine underwater. In this case, the torpedo breaks the sound barrier in air, not water.
