Is there any way to exploit a floating sand/gravel glitch in minecraft? Like lets say you have a solid block like dirt. And then you place a gravel or sand block high above it, and just as it touches the dirt block you destroy it and then the sand/gravel floats?

Has anyone ever done this before? Are there any ways of doing this?

Rather than trying to do it in-game, you can use MCEdit to achieve the same effect. In MCedit, select an area of air and use the Fill & Replace tool to select sand. Save your world, and voila: floating sand.

Floating sand

Apparently, sand doesn't start falling until it's interacted with.

There's also a weird interaction between sand and torches, in that sand will float above a torch:

And since water puts out torches (I think, right? Tell me I'm not going crazy!) you can use redstone-activated water to trigger sand cave-in traps. This'll get even easier next patch with pistons. – Raven Dreamer Jun 18 '11 at 5:05
@RavenDreamer Yup, that's correct. :) – Kevin Yap Jun 18 '11 at 5:10

minecraft also generates its own floating sand sometimes – user8949 Jun 18 '11 at 10:52
I once found a naturally occurring waterfall over a pool of lava. They didn't interact and form obsidian until I interacted with the lava, at that point the entire pool became obsidian. Not sure how to exploit that though. – l I Jun 18 '11 at 14:14

if you end off not being able to use/find an external world editor someone on a minecraft server showed me how to do this by using tall grass and putting the sand/gravel ontop of it then break the bottom of the grass and the top wont update the sand/gravel and this way you can do it in survival without cheating
