Hey guys, what's up? So I have a little thing today. Through my knowledge of Lucky Blocks, I figured some solutions out. The iron bars and the water, and I picked the easiest ways to get get out.

Obsidian-Glass Water:

 The easiest way out of it is digging through the block that is underneath you and block the water, you'll be safe. And dig underneath the obsidian, and get out.

UPDATE: It seems like this doesn't work anymore, so it will not work, but if you have a bucket, you can easily get out of it.


Iron bars, both anvil and lava.




Get any block, and place it on the top, will either stop the lava flowing onto you, or the anvils falling on you.
Then mine the iron bars so you can get out.



Falling into a cobweb, then into lava:
There should be stone next to you. Mine a 2x1 thing so you can fit in, then go inside that hole that you just made. Now you have to mine all the way up... That is the bad part.



Thanks for reading.
