 * If lava flows horizontally against water, the lava will solidify to Cobblestone.
 * If water flows horizontally against lava, nothing happens.
 * If water flows vertically into lava, cobblestones forms or nothing happens.
 * If water flows into a lava source block, the lava will solidify into Obsidian.
 * If vertically falling water touches the lava source block on any side, the lava will solidify into Obsidian.
