So, it's very easy to do.All you have to do is choose a place in your house which is connected with two doors. You have to stand at first door and say 'button world' three times and walk through the the first and second world.

When you are out through the second world you are in button world. In button world you can see yourself with button instead of eyes

To get back to normal world say 'normal world' three times with second door and exit from first door
