On june 29 2014, i tried to create a teleporting machine in vanilla. It didn't work very well. I used a comparator and redstone at the last minute... and BOOM the machine went bad. It kept teleporting me to a location. I had keepInv on so i spammed /kill. First i tried to hit it. Then blow it up. Then I finally saw the water in my inventory and griefed it! i waited for it to TP me, and it didn't. Goodbye evil machine!
