I've made explosions that behave like real explosions - mayhem with blocks flying in all directions, kicking up dirt and stone all over the place! So much fun!

This is a command block invention for Vanilla Minecraft 1.8.*, and you can get it either by downloading an MCEdit schematic file or by pasting one command into a command block as shown in the video.

After getting the blocks, press the button under the "Press to Install" sign, and you're good to go.

You can get the "one command" here.
