if you sit on a strider that stands on lava and place a boat such as he would sit on when the boat is destroyed you will not be on the strider and somthing weird happens.

when you press shift the game will teleport you to the strider and you will fall to the lava.

when you do this you cant destroy blocks that are more then 5 blocks away from the strider.

but you can place blocks at at least 8 blocks away.

if you travel like that you cant take damage.

if you travel to the end of the loaded chunk then the game wont load any new once.
