Explosive Splash Bottle

The Explosive Splash Bottle can be thrown like a splash bottle but explodes whenever it touches a block or entity (including players) without needing to be ignited. Its crafting recipe is this:

Copper Ingot          Gunpowder          Copper Ingot

Copper Ingot    Splash Water Bottle   Copper Ingot

Copper Ingot        Copper Ingot          Copper Ingot

Like TNT, this item will have an explosion power of 4, which can be increased by putting it in a crafting grid along with up to 9 gunpowder. Each gunpowder added will increase its explosion power by 1.

Also, when crafting this item, you can swap out one of the copper ingots with a fire charge to make it so anything near the explosion radius will catch fire.

This item will be a good option for an explosive when you don't have flint and steel. Also, it can be good for PvP.
