Sand Physics
by Multyfora
Sand Physics gives falling blocks such as sand, gravel, dripstone and concrete powder real physics through Sable, so they tumble and land instead of snapping into place.
What it does
Sand Physics applies physics to gravity-affected vanilla blocks, covering several sand and gravel variants, falling dripstone, concrete powder and the dragon egg. Once a block is affected it moves through the world as a physics object, and it can later be disassembled back into ordinary blocks when it lands. A configuration file controls how long a landed block waits before it disassembles.
Thrown or dropped physics objects can hurt players and mobs: anvils and dripstone deal damage on impact, and players can throw anvils or shoot dripstone at targets. The mod requires Sable for its physics engine, so Sable must be installed on the same side as Sand Physics. Sand Physics is published for NeoForge 1.21.1 only, with the latest file 0.3 dated 2026-07-15, and it runs on client and server, so both the server and every player need it. The code is open source under the MIT License.
Key features
Physics for falling blocks
Gravity-affected blocks such as sand and concrete powder fall and tumble using Sable's physics system.
Disassembly after landing
Physics blocks can turn back into regular blocks after landing, with the delay set in the config file.
Damaging physics objects
Anvils and falling dripstone deal damage to players and mobs when they hit them.
Throwing and shooting
Players can throw anvils and shoot dripstone, turning those physics objects into projectiles.

Use cases
Who it’s for: Players who want falling blocks to behave with physics, and server owners who run adventure maps or survival worlds where collapsing blocks and thrown objects matter. Sable must be installed alongside it.
How it compares
Falling Trees Physics is a server-side mod for NeoForge 1.21 – 1.21.11 under the MIT License, so players can join without it; it targets trees rather than falling blocks. Dragged's Simulated Tree Chopper is a client and server mod for NeoForge 1.21.1 under All rights reserved and is not open source. Block Modifier is client and server for 1.21.1 under the MIT License. Sand Physics is client and server for 1.21.1 only, with falling blocks and thrown physics objects as its focus.
