=== Piston crushing ===
[[Piston|Pistons]] have added functionality when placed so that when they extend towards [[obsidian]] with another [[block]] in the way, the obstructing block is destroyed and dropped in its existing state. This allows you to get normally unobtainable items such as [[ice]] without using golden tools. It can also be used for certain farm designs, such as ice farms, [[cobblestone]] farms and [[tree]] farms, so that blocks can be harvested semi-automatically or completely automatically, depending on the farm's design.

Immovable blocks, such as active [[Mob Spawner|mob spawners]], as well as blocks which are destroyed when pushed with pistons such as cobwebs and tall grass cannot be broken using this method.

Added in [[Beta 1.7.5]].

=== Cobblestone generation ===
The type of cobblestone generated is based on the lava's distance from the water.
