Gravity

Gravity - Dirt, Grass, Cobblestone

Gravity is now kind of a thing in Minecraft. When you place a floating block of dirt, grass or cobblestone it falls straight down as a falling block. When you break the block below a dirt, grass or cobblestone, the block above turns to falling block mode. This can be triggered in most ways. Cobblestone can also be triggered by softening the rock underground.
