# Slingshot

A slingshot or catapult is a small hand-powered projectile weapon. The classic form consists of a Y-shaped frame, with two tubes or strips made from either a natural rubber or synthetic elastic material. These are attached to the upper two ends. The other ends of the strips lead back to a pouch that holds the projectile. One hand holds the frame, while the other hand grasps the pocket and draws it back to the desired extent to provide power for the projectile—up to a full span of the arms with sufficiently long bands.
Other names include catapult (United Kingdom), peashooter (United States), gulel (India), kettie (South Africa), or ging, shanghai, pachoonga (Australia and New Zealand)

## Use and history

Slingshots depend on strong elastic materials for their projectile firepower, typically vulcanized natural rubber or the equivalent such as silicone rubber tubing, and thus date no earlier than the invention of vulcanized rubber by Charles Goodyear in 1839 (patented in 1844). By 1860, this "new engine" had established a reputation for use by juveniles in vandalism. For much of their early history, slingshots were a "do-it-yourself" item, typically made from a forked branch to form the Y-shaped handle, with rubber strips sliced from items such as inner tubes or other sources of good vulcanized rubber, and using suitably sized stones.
While early slingshots were most associated with young vandals, they could be effective hunting arms in the hands of a skilled user. Firing projectiles, such as lead musket balls, buckshot, steel ball bearings, air gun pellets, or small nails, a slingshot was capable of taking game such as quail, pheasant, rabbit, dove, and squirrel. Placing multiple balls in the pouch produces a shotgun effect (even though not very accurate), such as firing a dozen BBs at a time for hunting small birds. With the addition of a suitable rest, the slingshot can also be used to shoot arrows, allowing the hunting of medium-sized game at short ranges.
While commercially made slingshots date from at latest 1918, with the introduction of the Zip-Zip, a cast iron model, it was not until the post–World War II years that slingshots saw a surge in popularity, and legitimacy. They were still primarily home-built; a 1946 Popular Science article details a slingshot builder and hunter using home-built slingshots made from forked dogwood sticks to take small game at ranges of up to 9 m (30 ft) with No. 0 lead buckshot (8 mm [0.32 in] diameter).
The Wham-O company, founded in 1948, produced the Wham-O slingshot. It was made of ash wood and used flat rubber bands. The Wham-O was suitable for hunting, with a draw weight of up to 200 newtons (45 pounds-force), and was available with an arrow rest.
The National Slingshot Association was founded in the 1940s, headquartered in San Marino, California. It organised slingshot clubs and competitions nationwide. Despite the slingshot's reputation as a tool of juvenile delinquents, the NSA reported that 80% of slingshot sales were to men over 30 years old, many of them professionals. John Milligan, a part-time manufacturer of the aluminium-framed John Milligan Special, a hunting slingshot, reported that about a third of his customers were physicians.
Slingshots are also occasionally used in angling to disperse bait over an area of water, so that fish may be attracted.
A home-made derivative of a slingshot also exists, consisting of a rubber balloon cut in half and tied to a tubular object such as the neck of a plastic bottle, or a small pipe. The projectile is inserted through the tube and into the cut balloon, and the user stretches the balloon to launch the projectile. These so-called "balloon guns" are sometimes made as a substitute to ordinary slingshot, and are often used to create the "shotgun" effect with several projectiles fired at once.
In modern times the slingshot has been used by civilians against governments. Examples of this are Hong Kong during the 2019-2020 protests where they were used against the Hong Kong Police Force, by the Palestinians against Israeli forces. and by the Ukrainians during the Maidan Revolution in 2014.

## Military use

Slingshots have been used as military weapons, but primarily by guerrilla forces due to the easily available resources and technology required to construct one. Such guerrilla groups included the Irish Republican Army; prior to the 2003 invasion of Iraq, Saddam Hussein released a propaganda video demonstrating slingshots as a possible insurgency weapon for use against invading forces.
Slingshots have also been used by the military to launch unmanned aerial vehicles (UAVs). Two crew members form the fork, with an elastic cord stretched between them to provide power to launch the small aircraft.
On the Battle of Marawi, the soldiers of the Philippine Army's elite Scout Rangers were observed using slingshots with grenades as an improvised mortar to attack Maute and Abu Sayyaf forces.

## Sport

Slingshots, often recognized as tools or toys, are also utilized in various organized sports around the world. Competitive slingshot shooting, or catapult shooting, is gaining popularity, with events held in countries like Spain, Italy, and China. The Slingshot World Cup is one of the most prestigious competitions, attracting participants globally who demonstrate their accuracy and skill by aiming at various targets.
Competitions and Events
* Slingshot World Cup: This premier event draws competitors from across the globe, focusing on target shooting to earn points based on accuracy.
* National Championships: Many nations, including the USA, Spain, and Italy, host their own national championships, featuring various categories and age groups.
Types of Competitions
* Target Shooting: Participants aim at stationary or moving targets, which can vary in size and distance.
* Field Shooting: This involves shooting at targets set in natural environments, simulating real hunting scenarios.
Equipment
* Slingshots: Modern slingshots are crafted from high-quality materials such as aluminum and steel. Shooters often customize their equipment with different bands and pouches to match their preferences.
* Ammunition: Common types of ammunition include steel balls, marbles, and biodegradable pellets, which cater to eco-friendly practices.
Skills and Techniques
* Accuracy: Precision is paramount in slingshot sports, and participants dedicate time to improve their aim and consistency.
* Stance and Grip: Proper stance and grip are essential for stability and control, leading many shooters to develop unique styles.
Community and Culture
* Clubs and Associations: Numerous slingshot clubs and associations exist worldwide, providing enthusiasts with opportunities to share tips, participate in events, and promote the sport.
* Online Presence: The slingshot community is active online, with forums, social media groups, and YouTube channels dedicated to techniques, reviews, and competition highlights.
Overall, slingshot sports blend tradition with modernity, making them an engaging and accessible activity for people of all ages.

## Dangers

One of the dangers inherent in slingshots is the high probability that the bands will fail. Most bands are made from latex, which degrades with time and use, causing the bands to eventually fail under load. Failures at the pouch end are safest, as they result in the band rebounding away from the user. Failures at the fork end, however, send the band back towards the shooter's face, which can cause eye and facial injuries. One method to minimize the chance of a fork end failure is to utilize a tapered band, thinner at the pouch end, and thicker and stronger at the fork end. Designs that use loose parts at the fork are the most dangerous, as they can result in those parts being propelled back towards the shooter's face, such as the ball attachment used in the recalled Daisy "Natural" line of slingshots (see image). The band could slip out of the slot in which it rested, and the hard ball in the tube resulted in cases of blindness and broken teeth. Daisy models using plain tubular bands were not covered in the recall, because the elastic tubing does not cause severe injuries upon failure. Another big danger is the fork breakage; some commercial slingshots made from cheap zinc alloy may break and severely injure shooters' eyes and face.

## Legal issues

Many jurisdictions prohibit the use of arm-braced slingshots. For example, New York Penal law 265.01 defines it as a Class-4 misdemeanor, and in some states of Australia they are also a prohibited weapon.
