How to Build a Black Powder Charge for Gasoline Mine Fireballs
If you're looking to take your fireworks show to the next level, gasoline mine fireballs deliver an unforgettable visual punch. At ThermaBoom, we specialize in professional-grade mines—and today, we're walking you through how to build a black powder charge to fuel your next spectacular display.
🔥 What Is a Gasoline Mine Fireball?
A gasoline mine is a device that uses a black powder charge to eject gasoline in a high-pressure fireball that looks like a Hollywood explosion. It’s loud, bright, and totally unforgettable.
The key to a successful mine? A well-built black powder charge with a precise ratio, reliable ignition, and safety-focused assembly.
These are 1 Gallon Mines
🔧 What You’ll Need:
Black powder (1.25 oz per gallon of fuel)
PET bottle (2–16 oz)
E-match igniter
Epoxy or hot glue
Optional: Titanium flake for sparkles
Water & gasoline
⚙️ Quick Steps:
Drill the cap to fit your igniter snugly.
Seal the hole inside and out.
Add black powder, and optionally a pinch of titanium.
Attach the igniter, cap tightly, and secure it to the bottom of the mine.
Add 1.5” of water, then fill with gasoline (leave 1” space).
Cover with foil and tape to prevent stray sparks.
Remote fire only using Ignite, Cobra, or similar.
💥 Why It Works
The black powder ignites, launching a gas-and-water fireball sky-high. Add titanium for a sparkling rain effect. These mines are safe (when built right), legal (check your state), and unforgettable.
