Minecraft wiki entry for Diamonds, associated text: Blowing up TNT is one of the fastest ways to mine, but it does require a player to kill a large number of creepers for gunpowder and obtain lots of sand. Given a generous amount of TNT, a player can blow up one at a time, detonate a large clump, or place a block every five meters. TNT drops 100% of its items in Java edition, but this method is not viable in Bedrock edition.
