TNT Types

Lightning TNT

Makes a slightly bigger explosion and strikes lightning! Try digging deep under someone's pig pen and detonating one. That'll be a surprise :D

Making it

A diamond block on top of a TNT block.

Hailstorm Bomb

Launches the affected blocks in every direction. (Don't detonate it in bedrock :P but seriously. EVERY BLOCK.) Yes, I did motion-blur that picture. But those blocks do actually move.

Making it

Emerald block on bottom, TNT in the middle, Emerald block on top, and Iron blocks on the remaining sides of the TNT.

Nuke

Destroys a lot. Also poisons and blinds nearby players and mobs. The crater would be bigger, but the explosion algorithm fails. As you can see, there are assorted holes in the terrain and bare dirt where the grass blocks on top were stripped off.

Also, see that cow on the hill? It was poisoned down to half a heart. I punched it once and it died.

Making it

A block of TNT with emerald blocks on the front, back, and sides.

Nuclear Pigs

Spawns pigs that explode after a few seconds. 'nuff said.

Making it

Iron block on the bottom, TNT in the middle, Iron Block on the top, wool on the sides of the TNT.
