Bang snaps (known as poppers; whipper snappers, Indian English: pop pop crackers) are a type of small novelty firework sold as a trick noisemaker. [1]
Bang snaps consist of a small amount of gravel or coarse sand impregnated with a minute quantity (~0.2 milligrams) [2] of silver fulminate high explosive and twisted in a cigarette paper to produce a shape resembling a cherry. The friction-sensitive silver fulminate detonates when stepped on, ignited, or thrown on a hard surface, producing a sharp salute similar to a cap gun's.
Despite producing a legitimate (albeit tiny) high-explosive detonation, the extremely high mass ratio of gravel to explosive acts as a buffer to ensure that they only produce the audible "crack" of the supersonic shockwave; they are incapable of producing physical damage, even when discharged in the hand. [3] The explosion is unable to propel the gravel any distance, which usually falls to the ground, making them safe for use as a children's toy, for which purpose they have been widely sold around the world since the 1950s. They are also a common part of Chinese New Year celebrations.
Bang snaps are primarily produced alongside other export fireworks in Brazil, South Korea and China and are widely available over the counter at small toy stores and shops specializing in jokes, novelties and magic tricks. The snaps are typically packed in sawdust to prevent them from discharging due to rough handling while in transit.
Some US states and counties impose the same age restrictions on purchasing bang snaps as that of permitted fireworks, usually 17 or 18.[ citation needed ]
In the UK they are advertised as fun snaps, and sold only to people 16 or above. [4]

An explosive is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances.
Fireworks are low explosive pyrotechnic devices used for aesthetic and entertainment purposes. They are most commonly used in fireworks displays, combining a large number of devices in an outdoor setting. Such displays are the focal point of many cultural and religious celebrations, though mismanagement could lead to fireworks accidents.
A detonator is a device used to make an explosive or explosive device explode. Detonators come in a variety of types, depending on how they are initiated and details of their inner working, which often involve several stages. Types of detonators include non-electric and electric. Non-electric detonators are typically stab or pyrotechnic while electric are typically "hot wire", exploding bridge wire or explosive foil.
The percussion cap, percussion primer, or caplock, introduced in the early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition. Its invention gave rise to the caplock mechanism or percussion lock system which used percussion caps struck by the hammer to set off the gunpowder charge in rifles and cap and ball firearms. Any firearm using a caplock mechanism is a percussion gun. Any long gun with a cap-lock mechanism and rifled barrel is a percussion rifle. Cap and ball describes cap-lock firearms discharging a single bore-diameter spherical bullet with each shot.

A yo-yo is a toy consisting of an axle connected to two disks, and a string looped around the axle, similar to a spool. It is an ancient toy with proof of existence since 440 BC. The yo-yo was also called a bandalore in the 17th century.
Potassium chlorate is the inorganic compound with the molecular formula KClO3. In its pure form, it is a white solid. After sodium chlorate, it is the second most common chlorate in industrial use. It is a strong oxidizing agent and its most important application is in safety matches. In other applications it is mostly obsolete and has been replaced by safer alternatives in recent decades. It has been used
A firecracker is a small explosive device primarily designed to produce a large amount of noise, especially in the form of a loud bang, usually for celebration or entertainment; any visual effect is incidental to this goal. They have fuses, and are wrapped in a heavy paper casing to contain the explosive compound. Firecrackers, along with fireworks, originated in China.
Silver fulminate (AgCNO) is the highly explosive silver salt of fulminic acid.
The lock of a firearm is the mechanism used to initiate firing. It is generally used as a historical term, referring to such mechanisms used in muzzle-loading and early breech-loading firearms, as modern firearms uniformly fire by use of a firing pin to strike the rear of a cartridge. Side-lock refers to the type of construction, in which the individual components of the mechanism are mounted either side of a single plate. The assembly is then mounted to the stock on the side of the firearm. In modern firearm designs, the mechanism to initiate firing is generally constructed within the frame or receiver of the firearm and is referred to as the firing or trigger mechanism.
A cherry bomb is an approximately spherical exploding firework, roughly resembling a cherry in size and shape. Cherry bombs range in size from three-quarters to one and a half inches in diameter.
Armstrong's mixture is a highly shock and friction sensitive primary explosive. Formulations vary, but one consists of 67% potassium chlorate, 27% red phosphorus, 3% sulfur, and 3% calcium carbonate. It is named for Sir William Armstrong, who invented it sometime prior to 1872 for use in explosive shells.
A cap gun, cap pistol, or cap rifle is a toy gun that creates a loud sound simulating a gunshot and smoke when a small percussion cap is ignited. Cap guns were originally made of cast iron, but after World War II were made of zinc alloy, and most newer models are made of plastic. Cap guns get their name from the small discs of shock-sensitive explosive compounds that provide the noise and smoke, effectively the same as the Maynard tape primer and percussion caps used in real firearms of the mid to late 1800s but usually smaller and made from cheap plastic or paper. Some are arranged in plastic rings of eight or twelve. There are also single caps, roll caps, disk caps, and cap strips all of which are actually extremely small versions of percussion fireworks. Armstrong's mixture is often used today as the explosive, but previously the tiny powder charge was a simple mixture of potassium perchlorate, sulfur, and antimony sulfide sandwiched between two paper layers that hold in the gases long enough to give a sound report when the cap is struck.
Police Story 2, also known marketed as Police Story Part 2 is a 1988 Hong Kong action comedy film starring and directed by Jackie Chan, who also wrote the screenplay with Edward Tang. It is a sequel to the hit 1985 film Police Story, continuing the storyline of Chan's character "Kevin" Chan Ka-kui, and is the second installment of Police Story series. It also marks the last appearance in the series for Lam Kwok-Hung as Chief Inspector Raymond Li, Chor Yuen as Chu Tao and Charlie Cho as John Ko.
A contact explosive is a chemical substance that explodes violently when it is exposed to a relatively small amount of energy. Though different contact explosives have varying amounts of energy sensitivity, they are all much more sensitive relative to other kinds of explosives. Contact explosives are a part of a group of explosives called primary explosives, which are also very sensitive to stimuli but not to the degree of contact explosives. The extreme sensitivity of contact explosives is due to either chemical composition, bond type, or structure.
A cymbal-banging monkey toy is a mechanical depiction of a monkey holding a cymbal in each hand. When activated it repeatedly bangs its cymbals together and, in some cases, bobs its head, chatters, screeches, grins, and more. There are both traditional wind-up versions and updated battery-operated cymbal-banging monkeys. The cymbal-banging monkey toy is an example of singerie and kitsch.
Consumer fireworks are fireworks sold for use by the general public. They are generally weaker in explosive power than the fireworks used in professional displays.
The Big-Bang Cannon, also known as the Calcium Cannon, is an American toy cannon first manufactured in the early 20th-century. Numerous consumer fireworks injuries convinced a physics professor at Lehigh University in Bethlehem, Pennsylvania to patent a "Gas Gun" in 1907, and the manufacturing of Big-Bang Cannons started in 1912, from the Gas Cannon Company.
M-80s are an American class of large powerful firecrackers, sometimes called salutes. M-80s were originally made in the mid 20th century for the U.S. military to simulate explosives or artillery fire. The "M" is designated by a U.S. military convention for "standard" equipment and "80" is for the 80 grains of flash powder within it. Later, M-80s were manufactured as consumer fireworks made from a small cardboard tube, often red, approximately 1+1⁄2 inches (3.8 cm) long and 9⁄16 inch (1.4 cm) inside diameter, with a fuse coming out of the side; this type of fuse is commonly known as cannon fuse or Visco fuse, after a company responsible for standardizing the product. The consumer version holds a reduced charge of 45 grains of pyrotechnic flash powder.
Fireworks policy in the United States can be different in each jurisdiction.
