This is a glitch I found on minecraft pe 8.0 you can see every thing that has happened under ground and it also works on xbox 360

Step 1:

First dig a hole down about 15-20 blocks
Cool thanks
You can also use 2 sticky pistons, 2 blocks of TNT, and a lever to get the same effect.
Ok cool glad you like
cool. And if you fill the shaft in behind you, you can see all around. PS if you use another kind of block (ie stone) its like you get your head stuck in a block.
