How To Make a Cobblestone Generator!

Cobblestone Generators are the key part of SkyBlock, they allow us to build the best cobblestone bases known to man. I know that when I first started playing I barely knew how to create one and it ended up in many many many quit worlds, so that is why I would love to teach you it in 4 easy steps. 

Step 1- You need to dig a trench that is 4 blocks wide, and then on either of the second blocks (depending on how you look at it) dig down by one block. 

Step 2- Place water on the block that has three sides to it and also has the deeper hole. 

Step 3- Place lava on the complete opposite side and then cobblestone should appear. 

Step 4- GET MINING!

Hope this helps and piece out, Qwelksy :)
