How To Use The Bubble Gun | Setup, Prime, And Start

For the full breakdown, see our best Bubble Gun guide.

Getting a bubble gun running comes down to a short setup routine: batteries first, then solution, then a quick prime. Most consumer models, including the EagleStone AL20342, follow the same basic sequence. Here’s the step order that works, along with the mistakes that keep the bubbles from flowing.

What You Need Before Starting

Check the box before you begin. Most bubble guns list their requirements on the packaging, but a few items show up across nearly every consumer model:

• Batteries: typically AA or AAA, often two or more.
• Bubble solution: the refill bottle that came with the gun, or any standard bubble concentrate.
• A dry, open space: indoors or out, with nothing overhead you mind getting wet.

Set the gun on a flat surface and confirm the battery door is dry before opening it.

Installing Batteries And Adding Solution

Open the battery compartment on the handle or body, insert the batteries according to the polarity marks inside, and close the door securely. A loose battery door is a common reason a new gun does nothing.

Next, fill the solution reservoir. If your model uses a separate bottle that attaches to the gun — the EagleStone AL20342 does — fill that bottle and attach it with the gasket seated properly. The intake tube needs to sit fully inside the bottle; a crooked attachment leaves the tube above the solution line, and the gun will spin its fan without producing bubbles. Do not overfill, and press the bottle until it clicks or seats firmly.

If the connection is loose, you get air instead of bubbles.

Powering On And Priming

Flip the power switch to the on position. The fan should spin up immediately. If it doesn’t, the batteries are the first suspect — recheck polarity and try fresh cells.

For bottle-fed models, prime before first use. The first burst may be uneven; that clears quickly once the tube is wet.

Once primed, press the trigger to produce bubbles. Some models produce bubbles only while you hold the trigger; others run continuously once pressed. Either is normal. Aim upward or into open space, and keep the gun away from faces, pets, and anything electrical.

Cleaning, Storage, And Troubleshooting

Bubble guns are not waterproof. Never submerge the device — the motor and battery contacts will corrode. Wipe the exterior with a damp cloth after use, and let it dry before storing.

For long-term storage, remove the batteries. The most frequent cause of a dead gun after a season in a closet is battery leakage, not a broken motor.

Weak or absent bubbles usually trace to one of three causes:

• Power: batteries installed backwards, low cells, or a battery door that isn’t fully closed.
• Solution: an empty reservoir, an overfilled bottle that won’t seat, or a misaligned intake tube.
• Clogged nozzle: dried solution can block the opening. Clear it gently with a pin or by rinsing the nozzle under running water, then drying it fully.

If the fan spins but no bubbles form, the issue is almost always solution delivery, not the motor.
