Liquid pyrotechnics are fireworks that rain colorful, paint-like liquid when they explode. Princess Bubblegum created them sometime prior to the episode "Incendium," through a method called "cloud seeding." She then sets them off on the top of the Tree Fort. Flame Princess later accidentally lights them at the end of the episode. The subsequent rain causes her to pass out.
- They appear in Finn and Jake's Epic Quest as an Enchiridion page under the name of "PB's Paintworks."
- In Royal Ruckus they are contained in treasure chests and add to your final score.
