The modern, multi-coloured plastic water guns are a familiar sight, and you probably wouldn't be surprised to find out they've been around for a while. That said, it might surprise you to learn that records show they likely pre-date the American Civil War, at least in some form or another.
Back in 1861, Abraham Lincoln called for 75,000 volunteers to fight in the war. Boys were scrambling over each other trying to enlist first for fear that they might miss the conflict. They were doing the same thing in the South. William Tecumseh Sherman didn't think that Lincoln's estimate about how many men they'd need was adequate, and is quoted as saying, "Why, you might as well attempt to put out the flames of a burning house with a squirt-gun."
Savour that image of Abe running around in his top hat with a neon green and yellow Super Soaker in hand, because that isn't what squirt guns looked like back in the day. In fact, we can't know for certain exactly what it was that Sherman was referring to because the first documented squirt gun wasn't officially patented until a few decades later in 1896. That said, we can get a pretty good idea of what Sherman meant by looking at the earliest "USA Liquid Pistol."
The toy gun was made from cast-iron and was threaded through with tubing attached to a squeeze bulb not unlike that of an eyedropper. You would have to fill up the bulb, then squeeze it for the water to come out. Subsequent models used the trigger to squeeze the bulb and make the water shoot out.
Funny enough, the toy was marketed as an early sort of "pepper spray." In a 1905 ad, the makers of the USA Liquid Pistol advertised that the gun "will stop the most vicious dog (or man) without permanent injury." More effective than shooting an attacker with the squirt gun probably would have been throwing the cast iron weapon at the attacker's head. But nonetheless, this was just the beginning of generations of children's summer fun.
Much later, the cast-iron guns turned into the plastic ones that we know today. Rather than having an eye-dropper-like pouch, they also evolved to work more like spray-bottles. Pull the trigger, and the pressure causes water to come out of the barrel.
From here, squirt guns remained largely unchanged until 1977. That's when the first air-pressure pump water gun went on the market. It was called the Cosmic Liquidator and it worked by pumping air into the gun, building up pressure that was released when the trigger was pulled, resulting in a stream of water. It sounds a lot like the Super Soakers we know today, except that the pressure tank was motorised separate from the gun, connected by a bit of tubing. The batteries to keep the motor running were quite expensive, so it wasn't the ideal toy.
Finally, in 1989, the first Super Soaker was released. The model, the brainchild of mechanical and nuclear engineer Lonnie Johnson, was several years in the making. It all started in 1982 when Johnson had an idea to make a high-performance water gun. He was working as a spacecraft engineer for the Galileo Jupiter mission at the time. While doing some work on a heat pump that used water, he took the pump home and began playing around with it in his bathroom sink. He discovered that the pump could shoot water, and the stream of water was more powerful than any squirt gun he'd seen. Immediately he thought, "This would make a great water gun!"
Rather than have a motorised pump, Johnson developed an arm-powered pump like the one you know today. Pumping pressurised the firing chamber, and when the trigger was pulled, the water gun released more water faster than any of its previous counterparts.
However, Johnson was only a part-time inventor, which meant that he took a long time to develop the product. Once he did, he was unable to manufacture the gun himself due to limited resources. He decided to seek out a licensing agreement in 1985. Two companies were interested in the product. First, a company called Daisy wanted to take him up on it, but the gun sat on the waiting list for two years while the company underwent organizational restructuring.
Afterwards, he sought out Enertech, which already made motorised water guns. He went in with two other inventions, including a water-propelled toy aeroplane, and mentioned that his gun would blow their guns out of the water, so to speak. After giving them a demonstration, they were ecstatic with the product and decided to take it on. Unfortunately, they were having a rough time selling their toy guns due to a dislike of toy guns that looked like real guns. They went out of business before they had a chance to sell Johnson's new Super Soaker.
Finally, Johnson was able to make some adjustments to his prototype and present it to the company Larami in March 1989. The director loved it, and they started designing a prototype to manufacture soon after. The guns were on the market in 1990, and were a "top toy" in the first two years of sales. Johnson patented the product, which had several features — including the bottle water container — that became iconic of all types of water guns.
Afterwards, Johnson remained an innovative part of water guns' future. He and Larami continued to introduce improvements to the original Super Soakers, including larger water reservoirs and different triggers. In 2004, Soaker Tag was introduced — a game that involved wearing small target devices which blasted off if they were hit by water, allowing players to see who won and lost the game rather than simply shooting each other until everyone was soaked.
In 2010, the Super Soaker line merged with Nerf guns, resulting in additional innovations such as swappable water magazines, rotating nozzles, and tactical rails. Kids don't know how good they have it these days.
