Recently Rechenmaschine asked me whether it´s possible to get a ghost block of water.
This is just a quick video that shows a contraption that allows you to get a block that is water clientside, and tile-entityless block 36 serverside, which I think counts as a ghost block of water. The method can probably be adapted to disguise a block 36 as just about any other block that gets destroyed when pushed by a piston (although for most such blocks the contraption will be a bit messier, because the block will have to be placed by a player instead of a dispenser). I just wanted it to be publicly known somewhere that this kind of thing can be done.
The contraption is based on the fact , that since 1.11.2, when a piston destroys a block by pushing it, and when it creates block 36, it does not send any block modification packets to that block.
This means, that if you push an invisible block (i.e. a block that is air clientside and non-air serverside) into a destructible block, the block will get immediately destroyed serverside, but it will stay clientside, until the block 36 finishes its movement and sends new block modification packets.
Usually the block 36 finishes its movement 2 gticks later, but in this contraption we use a bug discovered by Smokey95dog ( youtube.com/watch?v=japKmrdZEic ) to destroy the tile entity of the block 36 so that it never finishes its movement, and thus we get a ghost block of water forever.

![TNT-Duplication based Quarry [Fixed in 1.9-pre 1]](https://i.ytimg.com/vi/6g_-HdKHBNg/hqdefault.jpg "TNT-Duplication based Quarry [Fixed in 1.9-pre 1]
This particular quarry has been fixed in 1.9-pre 1. If you want a quarry for a version after that use this instead: https://www.youtube.com/watch?v=8yrFNxOd_Lo
One could argue, that this is only a 2D Quarry and not a 3D Quarry, because it can only mine areas with a height of up to roughly 100 blocks, instead of being able to mine cubes of arbitrary height (because for anything bigger the tnt will explode before hitting the ground), but for practical intents and purposes this can do anything you would ever need from a quarry.

![Ghost Blocks [Fixed in 1.9]](https://i.ytimg.com/vi/7bbpTKMFQaE/hqdefault.jpg "Ghost Blocks [Fixed in 1.9]
I found a way to consistently make ghost blocks (blocks, that are there for the client, but not for the server) and the opposite, invisible blocks (blocks, that are there for the server, but not for the client) in 1.8. release. I considered it worth sharing.
And if you watch closely, you can see some very weird piston animations.

My theory on how this thing works (this thing is incorrect, but I´ll leave it here anyways. If you want a correct explanation watch the video Exploiting 1 tick desynchronizations):
When a piston facing upwards gets activated, it tells the block above it, to change to an extending piston head with the same damage value as the block below it (the piston) upon it´s next update. If we use fancy zero tick technology to replace the piston with another piston facing sidewards, before the block above gets updated, the block above the piston will also be a sidewards facing piston head, since it creates a piston head with the same damage value as the piston below it. So this machine creates a sidewards facing sticky piston head moving downwards above the normal piston facing upwards.
The client will just see: There is a sticky piston head retracting downwards. Therefore it will pull the block above the piston head downwards.
The server on the other hand in smarter, and recognizes that the sticky piston head is facing the wrong way and therefore will not pull the block above.
So for the client the blocks above the contraption are pulled down and for the server they aren´t. And these desynchronized blocks are, what we call ghost blocks.")

Earthcomputers Cluster Chunk Finder Program: https://github.com/Earthcomputer/FallingClusterFinderJava/releases
Steps for performing a chunk swap:
1. Activate permaloader and mob switches.
2. Load grid of cluster chunks.
3. Wait for an autosave.
4. All players simultaneously relog. Player at unload platform aligns against cobble wall while relogging.
5. Create invisible chunk. Fly towards beacon tower.
6. Player at unload platform flicks lever and goes through iron trapdoor. Immediately after that the player at the beacon tower place 2 layers of stained glass above the beacon tower.The players should not unnecessarily walk around or move their mouse while doing this.

Also thanks to TFirst for hosting a server on which I could record the video (if I load the cluster chunks on my own computer its so laggy that its unplayable).")
