I would like to mine lots of obsidian without paying a lot of attention. I was thinking about a 1X1 column of obsidian going straight to bedrock so could look down and put a weight on my track pad button.
What is the best way to make a 1X1 column of obsidian underground? I would prefer if I did not need a huge number of lava buckets. I was thinking maybe something about the redstone to obsidian glitch.
