How it Works
A straw like structure full of water with piston on top
Throw a ender pearl into the water
Pearl floats up
Activate the piston using a remote redstone signal to teleport back quickly (such as remote redstone interface, if chunk isn't loaded in then use a camera and a remote redstone)
Purpose
You can suspend the ender pearl and unsuspend it
Once remotely unsuspended you'll teleport back
