Mining obsidian is not only time consuming, but dangerous. Looking for caves with obsidian and risking death by creeper, zombie, or lava just isn't worth it sometimes. Luckily, obsidian can be farmed, just like cobblestone! You'll no longer need to put your life on the line for this most-indestructible of building materials.

Create a Controlled Water Flow

Excavation pit with stone base surrounded by dirt.

Since obsidian can only be made by lava contacting flowing water, you'll need to make a contained flow. Dig a hole three blocks wide and surround it with non-flammable blocks.

Waterfall in a stone and gravel landscape.

Place water so that it flows into the hole and nowhere else.

Water pool surrounded by dirt blocks in a game environment.

Place blocks on the opposite side of the water flow so that they enclose a three block wide trench just touching the flowing water.
