Instructions
Use a stone, iron or diamond pickaxe to mine any iron ore block to receive one iron ore for each mined block. You can distinguish an iron ore block from a regular block by the flecks of copper color in the block. Iron ore blocks are typically found below the surface of your Minecraft world. You will need three pieces of iron ore to make a bucket.
Combine the iron ore and a piece of coal or wood in any furnace to create an iron ingot. You will need three iron ingots to create a bucket.
Use a crafting table and place the iron ingots in the first and third, or outside, positions of the second row of the crafting grid and in the second, or middle, position of the third row to create the bucket. Your iron ingots should appear to be placed in a ̶0;V̶1; shape.
Equip the bucket. Once equipped, it displays on the right side of the screen.
Point the bucket at any body of water and right-click to hold the water in the bucket. Right-click again to pour the water out.
