firecracker

A firecracker is thrown with a right click and travels in the direction the player is facing. Smoke and spark particles trail behind it in flight. On impact it explodes instantly, whether it hits a block, an entity or the ground, and players can watch the bang from across the area.

Explosion effects are split into separate parts. The blast can damage blocks, so a firecracker can break things, but the mod can also be used as a purely visual effect that only plays particles and sounds and does not hurt players or mobs. Firecrackers that land in water turn into duds and produce bubbles instead of an explosion. Other players see thrown firecrackers as well, and the mod works in multiplayer.

The item is crafted from one cobblestone, one paper and one gunpowder, which yields eight firecrackers, and up to 64 stack in a single inventory slot. Firecracker is published for Fabric only, with files for 1.21.1 and 1.0.1 as the latest build dated 2026-07-31. The environment is client and server, so the server and every player need the mod, and the code is released under the zlib License without being open source.
