Summer used to be different. If you grew up before 1990, a water fight was basically a race to see who could get the garden hose first because the alternative was pathetic. You had these tiny, palm-sized translucent plastic pistols that leaked more water on your hand than they actually fired at your friends. They worked on a simple trigger-pump mechanism. You squeeze, a pathetic little squirt travels three feet, and then you’re out of ammo.
Then Lonnie Johnson happened.
The Super Soaker squirt gun didn't just iterate on a toy; it fundamentally applied the laws of thermodynamics and fluid dynamics to backyard warfare. Lonnie Johnson, a literal rocket scientist who worked on the Galileo mission to Jupiter and the stealth bomber, accidentally birthed the idea while working on a heat pump in his bathroom. He hooked a nozzle to the sink, filled a plastic bottle with air and water, and shot a stream across the room. He knew he had something. But the road from a PVC pipe prototype to the neon-green icon of the nineties was actually pretty messy.
The Air Pressure Revolution
Most people don't realize that the original Super Soaker wasn't even called that. It launched in 1990 as the "Power Drencher." It didn't sell well at first because nobody knew what it was. Larami, the company that took a chance on Johnson's invention, rebranded it in 1991, and the rest is history.
What made the Super Soaker squirt gun a literal game-changer was the pressurized reservoir. Instead of your finger doing the work of moving the water, your arm did the work of compressing air. You pump the handle, the air gets squeezed into a tight space above the water, and when you pull that trigger, all that stored potential energy turns into kinetic energy. It was the first time a kid could actually "snipe" someone from thirty feet away.
Actually, it was almost too powerful. Some schools tried to ban them. There were reports of kids getting hit in the eye and getting hurt because, honestly, these things packed a punch that the industry hadn't seen before.
The early 90s models like the SS50 and the legendary SS100 were sleek. They were mostly white with yellow and green accents. They felt like science equipment. If you had an SS100, you were basically the heavy artillery of the neighborhood. It held a liter of water. It was heavy. It was glorious.
Why the CPS Era is Still the Gold Standard
If you talk to collectors today—and yes, there are hardcore water blaster collectors—they don't usually talk about the air pressure models. They talk about CPS. Constant Pressure System.

In 1996, the Super Soaker CPS 2000 hit the shelves. If the original was a rifle, this was a fire hose. Instead of using air pressure in a plastic bottle, it used a thick rubber bladder. When you pumped water into the bladder, the rubber expanded. Because rubber wants to return to its original shape, it provides a consistent, high-pressure force on the water until the bladder is empty.
The result? A massive, thick stream of water that didn't trail off as the pressure dropped. It was relentless.
The CPS 2000 is often cited as the most powerful mass-produced water gun ever made. Rumors circulated for years that it was discontinued because it was "too dangerous," supposedly causing neck injuries or eye damage. While those stories are mostly urban legends fueled by the sheer power of the blast, the industry did eventually scale back the power levels. Modern blasters, even the expensive ones, rarely match the sheer "drench factor" of a mid-90s CPS unit.
The mechanics are simple but the execution was expensive. High-quality surgical tubing and durable housings cost money. As toy companies looked to maximize margins in the 2000s and 2010s, the complex rubber bladders started to disappear in favor of "pump-to-fire" mechanisms. These are the ones where there is no trigger—you just slide the handle back and forth to spray. It’s cheaper to make, but it ruins your aim. You can't hold a steady stream. It’s just not the same.
The Engineering Behind the Drench
Lonnie Johnson’s genius wasn't just the pressure; it was the nozzle design. A Super Soaker squirt gun needs a laminar flow—or as close to it as a plastic toy can get. If the water comes out turbulent, it breaks into a mist instantly. Mist doesn't travel. Mist doesn't soak.
To get distance, you need a cohesive stream.
- The nozzle must be perfectly circular with no burrs from the molding process.
- The pressure must be high enough to overcome air resistance.
- The volume of water (the "output") needs to be significant enough that the outer layers of the stream protect the inner core from breaking up.
This is why the "soaker" part of the name is so accurate. It wasn't about tagging someone with a drop of water; it was about making them go inside to change their clothes.

Spotting the Real Deal in a Sea of Knockoffs
Walking down the toy aisle today is depressing for a 90s kid. You see the brand name "Super Soaker" everywhere—now owned by Hasbro under the Nerf umbrella—but the tech has changed.
Most modern models are "syringe" style or simple air-pressure tanks that lack the build quality of the originals. If you're looking for that vintage performance, you have to look for specific features. Check the trigger. If the trigger is just a molded piece of plastic that doesn't move, and you have to pump to fire, it's a "flash flood" style blaster. It's fine for toddlers, but you'll lose every serious fight.
Look for a "separate pressure chamber." This is a smaller tank inside or attached to the gun where the air is actually compressed. If you're pumping air into the main water tank, the pressure will drop every time you fire a shot, and the tank becomes harder to unscrew when you need to refill. A separate chamber keeps the reservoir easy to manage.
Lonnie Johnson: More Than Just Toys
It's worth noting that the man who gave us the Super Soaker is a freaking powerhouse. Lonnie Johnson holds over 100 patents. He didn't just take his royalty checks and retire to a beach. He used the money from the Super Soaker and the Nerf dart gun (which he also helped revolutionize) to fund research into green energy.
He’s been working on the Johnson Thermo-Electrochemical Converter (JTEC). It's a system that converts heat directly into electricity with incredibly high efficiency. It’s basically the same high-level physics that allowed him to realize why a pressurized water tank would outclass a mechanical trigger pump, just applied to the world's energy crisis.
When you hold a Super Soaker, you're holding a piece of engineering history funded by the same mind that helped get a spacecraft to Jupiter. That’s why it feels different. It wasn't designed by a marketing committee; it was designed by a guy who understood how to make fluids do what he wanted.
Maintaining Your Blaster
If you manage to find a vintage CPS or an early air-pressure model at a garage sale, don't just fill it and fire. The O-rings are likely bone dry.

You need to use a little bit of silicone grease—not WD-40, which will eat the plastic—on the pump piston and the trigger valves. If it's a CPS model, be careful. Those rubber bladders can dry rot over thirty years. If you over-pump a dry bladder, it’ll snap, and then you’ve just got a very expensive piece of neon plastic.
Also, never leave water in the tank over the winter. Algae grows in there. It’s gross, it clogs the nozzle, and it smells like a swamp.
The Cultural Impact of the Soak
The Super Soaker changed the "meta" of childhood play. It shifted the game from "I got you" (which usually ended in an argument) to "You are clearly wet," which is an indisputable fact. It brought a level of objective truth to backyard games.
It also created a hobbyist community that refuses to let the high-pressure era die. Sites like Super Soaker Central have been around for decades, archiving every model and teaching people how to "K-Mod" their blasters. A K-Mod involves adding K-type latex tubing to the pressure chamber to increase the force. It’s basically overclocking a water gun.
Some of these modified blasters can shoot 50 or 60 feet. At that point, you're not playing with toys anymore; you're operating light machinery.
What to Look for When Buying Today
If you want the best possible experience with a modern Super Soaker squirt gun, you have to be picky.
- Avoid "Tactical" gimmicks: Rails and scopes on a water gun are useless. You're lobbing water in an arc; a red-dot sight isn't helping.
- Capacity matters: Look for a model that holds at least 1.5 liters. Anything less and you'll spend the whole afternoon at the tap.
- Check the seal: Flip the gun upside down. If it drips from the cap, it won't hold pressure. Simple as that.
- Battery Power? Some new models are motorized. They're fun because you get a "full auto" feel, but they rarely have the distance of a manual pump. Plus, mixing batteries and water always feels like a ticking clock on the toy's lifespan.
The Super Soaker remains a high-water mark of toy design because it was a perfect marriage of simple fun and sophisticated physics. It’s one of the few toys from that era that actually lived up to the TV commercial hype.
Actionable Next Steps for Backyard Dominance
If you're serious about winning your next water fight, stop buying the $10 grocery store specials and look for "high-capacity pressurized" models specifically. Check the secondary market for a CPS 1000 or 1200; they are often more durable and manageable than the legendary 2000 while offering 90% of the power. Always lubricate the pump handle with silicone lubricant before the first use of the season to ensure a smooth draw and prevent seal failure. When firing, aim for the chest rather than the face—not just for safety, but because the torso provides a larger surface area for the water to hit and "soak" in, ensuring your opponent is officially out of the game. For the ultimate advantage, keep a five-gallon bucket of water stationed as a "reload point" so you aren't tethered to a slow-running garden hose while you're being flanked.
