As you probobly know, Minecraft 1.8 snapshots are here... One of the things Mojang said about the lasted snapshot is that it has a new secret feature. I really wanted to know what it is, so I started searching. But for now, it seems to be that no one knows what it is. The only clue I found is this picutre, that Mojang gave it the wiki. Can anyone figure it out?
When block's break, the particles last longer? Idk, it looks like one of those particle effects that blocks create when they are broken. Or maybe command blocks can spawn particles :D
