1. From Munich: The “SpyraThree” That Redefines Water Guns

Kicking things off is the “SpyraThree,” which made waves in 2025 with a limited-edition collab with streetwear brand Supreme.
Its patented “Spyra Technology” delivers a single shot up to 10 meters and a Power Shot that nails targets up to 15 meters away.
An LCD display shows your water and battery levels at a glance, and refilling is lightning fast — just dip it in water and you’re full in about 10 seconds.

You’ll never have to mutter, “Aw, I’m out already…” again. It features three firing modes — League, Burst, and Open — all packed into one high-tech beast.
The price will make you say, “No way this is a water gun!” but it’s worth it for the ultimate summer showdown. Note: Due to its power, it’s recommended for ages 14+.

Older models go for a bit cheaper.

2. A Water Gun with Muzzle Flash and Recoil?!

This next one fires with an LED muzzle flash effect and a sliding, vibrating top section that amps up the “I’m actually shooting” vibe.
It’s insanely fast in full-auto mode, with a direct range of about 7 meters and a max range of around 8 meters.
At this point, can we still call it a water gun? For ages 8+.

👇 This is apparently the latest model featured in the video.

3. Shoots Forward AND Backward — Reverse-Spray Prank Gun

Cute on the outside, but with a mischievous twist — it can fire both forward and backward.
Pull the rear trigger for a forward blast, or pull the regular trigger to spray yourself in the face.
You can only fool someone once, but its normal firing range is a surprising 8 meters.
Low price, double the fun. Warning: Choose your prank target wisely.

4. Pushing the Limits — Electric Gatling Water Gun

Bring this to the park and you might get reported.
The Amazon product video is so intense it’s hilarious — this thing means business.
LED flash effects, an 8–10 meter range, and a backpack tank that holds a massive 2,500 ml of water.
Basically, a wet battle machine.

5. The Fireworks Fountain of Water Guns

After all these high-intensity monsters, let’s cool down with something more relaxing.
This one sprays water in a 360-degree pattern, creating a beautiful fountain effect like summer fireworks.
No Gatling barrels or rapid fire — just pure visual coolness.
