mess around with this in singleplayer or show it off on your server! you can look through glass to diamonds, emeralds, and gold. when you leave to get a closer look, it's GONE. how it works: there's really 2 viewing stands, one with the riches and one without. when you leave 1 viewing stand you tp to the one without riches, when you enter, u tp to the one with riches. IMPORTANT: use with render distance 2 chunks. otherwise it ruins everything  cuz 2 chunks means 32 blocks u need to see less than 40 blocks away.

Wanna see it? Gonna have to download it!
