Instructions: Change the command so that the shulker does not attack and add info about spawning falling blocks. Also add what to do with interactive blocks. Refer to the video for more info

First, enter creative mode so that you can mine the bedrock that borders the world and the void. You can then enter this hole to enter the void. Be sure you're in flying mode, though, as you will fall indefinitely otherwise.

You will then have to spawn shulkers using commands with /summon <minecraft:shulker> [spawnPos: x y z] {Invisible: 1b}, where x y z are the coordinates. The shulkers are meant for a hit box for the blocks. Notice there is a 0.5 (½) offset in spawning an entity, so put .5 at the end of the coordinate to direct it to a whole number.
