Minecraft: How to Make TNT
In Minecraft, you can use TNT to blow up blocks and cause some general havoc.
To make a block of TNT, you’ll need a Crafting Table, four blocks of Sand, and five pieces of Gunpowder which only drop from Ghasts and Creepers. Creepers are probably your best source of Gunpowder, since you don’t have to go to the Nether to find them.
Combine the ingredients into your Crafting Table as shown below to get your TNT block. You only get one block of TNT per combination.
