Exploding Fluid

"Erumpent horns, tails, and the Exploding Fluid are all used in potions, though classified Class B Tradeable Materials."

- Newton Scamander, Fantastic Beasts and Where to Find Them.

Exploding Fluid is found in the horn of the Erumpent. It causes anything that is impregnated with it to explode. It is highly valued as a potion ingredient, and is listed as a Class B Tradeable Material.

In 1998, an Erumpent horn in the Lovegood House was struck by a Stunning Spell. This caused the fluid inside to explode, causing significant damage to the dwelling.

Behind the scenes

 * In the handheld versions of LEGO Harry Potter: Years 1-4 Harry Potter had to get past a metal double-door in Knockturn Alley. He was given this Fluid to explode the door by a Mystic Wizard in exchange for two scarab beetles.
