I guess that is what it is called, anyway.
Build a high tower out of any block. Go up to any height you want, I am going for the max (128 blocks).
Crouch and jump. Then click on the up button
Step 3. Move away from the tower of blocks. You can now glide around. Simply press on down to go down and go down to land to land on the ground. Press crouch to stop crouching.
