World Record Cannon-Range

this cannon can break it just be patient with the charge time
no proper screenshots so that people can't willy nilly copy it cos it's tiny
also suggest doing /gamerule commandBlockOutput false before you start charging

pull the lever first and wait before pressing the button
also recommend replacing the projectile slab with a block if you want to use it practically (ie to blow stuff up xD)
a vertical version of this got me 27km in the air
haven't been able to measure the lateral distance it goes, but i know that even with 160ish charges it shoots more than a kilometer and the projectile speed is so high that it's invisible

tried to shoot it with 2160 charges and my computer crashed
if you have a powerful computer, post how far you got (preferably with proof)

reuploaded with a screenshot because the fun police didn't read the description
