Okay, so I was browsing YouTube again today, and I stumbled on an interesting little video that's roughly a year old.
If this had more views, I'd not even really bother posting it, but I'd take a guess that most of what happens in this video isn't exactly common knowledge. Enjoy! :D
Sadly mob AI got (reluctantly) updated in 1.9 so you can no longer hide in 2 tall plants and behind vines.

Don't throw your tall plants away just yet though, the magical floating sand trick still works!

this is very interesting, just to know it exists if nothing else
