Step 4:

Finnaly, place water first on either the 1st block in the hole, or the last bock in the hole (1st block if hole in 2nd, 4th block of hole in 3rd), and then place lava at the opposite end of the water. This should create cobblestone at the remaining block that is not covered. Break it, and then it respawns infinitely!

You know what to do.
