An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships, gliders, and hot air balloons.
Mouth-to-mouth resuscitation, a form of artificial ventilation, is the act of assisting or stimulating respiration in which a rescuer presses his or her mouth against that of the victim and blows air into the person's lungs. Artificial respiration takes many forms, but generally entails providing air for a person who is not breathing or is not making sufficient respiratory effort on his/her own. It is used on a patient with a beating heart or as part of cardiopulmonary resuscitation (CPR) to achieve the internal respiration.
A skyrocket is a type of firework that uses a solid-fuel rocket to rise quickly into the sky; a bottle rocket is a small skyrocket. At the apex of its ascent, it is usual for a variety of effects to be emitted. Sky rockets use various stabilisation techniques to ensure the flight follows a predictable course, often a long stick attached to the side of the motor, but also including spin-stabilisation or fins.
Circular breathing is a technique used by players of some wind instruments to produce a continuous tone without interruption. It is accomplished by breathing in through the nose while simultaneously pushing air out through the mouth using air stored in the cheeks.
A steel roller coaster is a roller coaster that is defined by having a track made of steel. Steel coasters have earned immense popularity in the past 50 years throughout the world. Incorporating tubular steel track and polyurethane-coated wheels, the steel roller coasters can provide a taller, smoother, and faster ride with more inversions than a traditional wooden roller coaster.
There have been several cases of whale carcasses bursting due to a buildup of gas in the decomposition process. Actual explosives have also been routinely used to assist in disposing of whale carcasses – ordinarily after towing the carcass out to sea. The most well known case of an "exploding whale" was an event at Florence, Oregon, in November 1970, when a dead sperm whale was blown up using dynamite by the Oregon Highway Division in an attempt to dispose of its rotting carcass. The explosion threw whale flesh over 800 feet (240 m) away. This incident became famous in the United States when American humorist Dave Barry wrote about it in his newspaper column in 1990 after viewing a videotape of television footage of the explosion. The event became well known internationally a few decades later when the same footage circulated on the Internet. It was also parodied in the 2007 movie Reno 911!: Miami and in the 2018 Australian comedy Swinging Safari.
A water rocket is a type of model rocket using water as its reaction mass. The water is forced out by a pressurized gas, typically compressed air. Like all rocket engines, it operates on the principle of Newton's third law of motion. Water rocket hobbyists typically use one or more plastic soft drink bottle as the rocket's pressure vessel. A variety of designs are possible including multi-stage rockets. Water rockets are also custom-built from composite materials to achieve world record altitudes.
A beach ball is an inflatable ball for beach and water games. Their large size and light weight take little effort to propel; they travel very slowly and generally must be caught with two hands.
Georges Christen is a Luxembourgish strongman. He holds 23 Guinness World Records, including the fastest hot water bottle inflated by lung power. Other records involve tearing up phonebooks, train-towing and plane-pulling.
Wallace and Gromit's Cracking Contraptions is a series of ten Wallace and Gromit stop motion animations varying in length from 1 to 3 minutes.

A ground burst is the detonation of an explosive device such as an artillery shell, nuclear weapon or air-dropped bomb that explodes upon hitting the ground. These weapons are set off by (fuses) that are activated when the weapon strikes the ground or something equally hard, such as a concrete building.
A dry ice bomb is a simple explosive device. While its simplicity, ease of construction, high bursting pressure and sound make it appealing for recreational purposes, it can be unpredictable and dangerous, and it has led to many injuries. Dry ice bombs are illegal in many jurisdictions.
This is a list of the world's record-breaking top speeds achieved by street-legal production cars. For the purposes of this list eligible cars are defined in the list's rules. This list uses a different definition to the List of automotive superlatives. The variation is because the term production car is otherwise undefined.
