I've been playing on the PPCG Minecraft server for a little while, and I've managed to build a fairly decent tower, but someone has decided to do this, right next to the top:
While I could build out and get it, I don't have a silk touch pickaxe, which means I'd have to make more glass, and I'd lose some resources due to the height as well.
Is there any way that I can destroy this block from afar? Do note, I don't have command privileges.
