Minecraft Pe, how to Make Secret Passage Walls

Hey guys what's up? My name is SmallSteveT!  Today is sadly going to be shorter, but is awesome!  Today I will be showing you how to make secret walls!  What do you need?  What do you need, well that's simple it's just one command block!  What can this be used for?  This can be used for making a secret passage to hide stuff from enemies or even friends!  What do you do with the command block?  Well everybody that knows about the command block should know that you just type in a command!  What command?  Well this is not long at all but here is the command:

/fill 100 64 102 100 65 102 stone_button 14

This should make a two-block tall, and one-block wide pillar of stone blocks, that you can walk through!  Just remember that you have to put the 14 in the command, and that you can break the block easily because it is two big stone buttons that you can walk through!  Pretty cool right?  I definitely think it is super cool!

I am sorry if you were disappointed about how short it was today. But that's it for today!  Goodbye!
