Slingshot

A slingshot is a small, hand-powered projectile weapon.

It is used to launch objects through the air using elastic energy. The classic design features a Y-shaped frame. Two tubes or strips of elastic material are attached to the upper ends of this frame. These strips are made from natural rubber or synthetic materials like silicone. The other ends of the strips connect to a small pouch. This pouch holds the projectile, which is the object being launched. To use it, one hand holds the frame steady. The other hand grasps the pouch and pulls it back. This action stretches the elastic material to provide power for the projectile.

The mechanism relies entirely on the properties of strong, elastic materials. Most modern slingshots use vulcanized natural rubber or silicone rubber tubing. Vulcanization is a process that makes rubber more durable and stretchy. Because of this requirement, slingshots only appeared after Charles Goodyear invented vulcanized rubber. He patented this process in 1844. When a user pulls the pouch back, they are storing potential energy in the stretched bands. When the user releases the pouch, that energy is quickly converted into kinetic energy. This energy pushes the projectile forward at high speeds. The amount of power depends on how far the user can pull the bands. With sufficiently long bands, a user might pull the pouch back to the full span of their arms.

Slingshots have been used in many different ways throughout history. For a long time, they were "do-it-yourself" tools. People would find a forked branch to serve as the Y-shaped handle. They would then slice rubber strips from items like inner tubes. While they were sometimes associated with juvenile vandalism by 1860, they were also effective hunting tools. A skilled user could hunt animals like quail, pheasant, rabbit, dove, and squirrel. They could use various projectiles, including lead musket balls, buckshot, steel ball bearings, or small nails. Some users even placed multiple balls in the pouch to create a "shotgun effect." This allows a dozen BBs to be fired at once, which is useful for hunting small birds.

Commercial production of slingshots changed how they were used and perceived. In 1918, a cast iron model called the Zip-Zip was introduced. Later, the Wham-O company began producing slingshots in 1948. Their model was made of ash wood and used flat rubber bands. This Wham-O slingshot was suitable for hunting and had a draw weight of up to 10 pounds. It even featured an arrow rest, which allowed it to shoot arrows at medium-sized game. In the 1940s, the National Slingshot Association was founded in San Marino, California. This organization helped organize clubs and competitions across the country. Interestingly, the association reported that 80% of slingshot sales were actually to men over 30 years old. Many of these buyers were professionals, such as physicians.

Slingshots are also used in specialized military and political contexts. Guerrilla forces often use them because the materials are easy to find. For example, the Irish Republican Army has used them. In 2003, Saddam Hussein even released a video showing slingshots as a possible weapon for an insurgency. During the 2014 Maidan Revolution in Ukraine, they were also used. In more recent times, they were used by civilians in Hong Kong during the 2019-2020 protests. The United States military has even used slingshots to launch unmanned aerial vehicles (UAVs). In this method, two crew members hold the fork and stretch an elastic cord between them to launch the small aircraft. In the Battle of Marawi, Philippine Army soldiers used slingshots with grenades as improvised mortars.

Today, slingshots are also used in organized sports. There are popular championships in Spain, Italy, and China. The Spanish Association of Sports Slingshots organizes these events. In international competitions, the standard distance from the participant to the target is ten metres.

Beyond sports, they are used in angling to disperse bait over water to attract fish. There is even a homemade version called a "balloon gun." This is made by cutting a rubber balloon in half and tying it to a tube, like a plastic bottle neck. The user stretches the balloon to launch a projectile through the tube.

Despite their uses, slingshots carry significant safety risks. The most common danger is the failure of the elastic bands. Most bands are made of latex, which degrades over time. If a band fails at the pouch end, it usually rebounds away from the user. However, if a band fails at the fork end, it can fly back toward the shooter's face. This can cause serious eye or facial injuries. Some designs are particularly dangerous. For example, the recalled Daisy "Natural" line used a ball attachment at the fork. If the band slipped out, the hard ball could cause blindness or broken teeth. Additionally, cheap slingshots made of zinc alloy can break, causing injury. Because of these risks, some places like New York and parts of Australia have laws prohibiting certain types of slingshots.
