How to Blow Up TNT in Minecraft

Cacti and lava are fun ways to kill, but if you want something more exciting and explosive, you're going to want to try out TNT. TNT is infamous for its use in traps and griefing. It can also be used to assist you while mining, though it might not be very effective. TNT is commonly used for traps and cannons only. Before creating complicated traps, it's best to learn how to blow up TNT in the first place.

Part 1

Part 1 of 3:

Making TNT

1
Find 5 pieces of gunpowder. You'll need 5 pieces of gunpowder in order to craft a piece of TNT. Gunpowder cannot be crafted, and must be found by defeating certain enemies that have a chance of dropping some, or looking in certain chests that have a chance of holding some:
- Defeating creepers (before exploding): 66% (1-2 gunpowder)
- Defeating ghasts: 66% (1-2 gunpowder)
- Defeating witches: 16% (1-6 gunpowder)
- Opening desert temple chest: 59% (1-8 gunpowder)
- Opening dungeon chests: 58% (1-8 gunpowder)
2
Get 4 sand blocks. You can use regular sand or red sand. Both work the same and can be mixed during the creation of TNT. You can find sand most commonly in the following biomes and areas:
- Beaches
- Deserts
- Riverbanks
- Mesa (red sand)

3
Open your crafting window. Use your crafting table to open the crafting grid.
4
Place the gunpowder in an "X" pattern. Place one gunpowder in each corner of the grid, then place the last piece in the center.
5
Fill the remaining spaces with sand (or red sand, or a combination of the two.) Place sand blocks in the four open spaces left in the grid. This will create TNT.
6
Add the TNT to your inventory. Drag the TNT from the result grid and add it to your inventory. You can now place it in your world to be blown up.^{[1]

Detonating with Fire

1
Use flint and steel to light a TNT block. This is the simplest way to detonate TNT.^{[2]
X
Research source} See Make Flint and Steel in Minecraft for instructions on crafting it. Walk up to the TNT with flint and steel equipped to light it. The TNT block will begin flashing when lit.
- Make sure to back up to a safe distance before it explodes (4 seconds after being lit).
- TNT has an explosive radius of about 7 blocks.
2
Use a flaming arrow to light the TNT. If you want to be a little safer when setting off your TNT, you can use a flaming arrow to light it.^{[3]

Research source}
- You can enchant your bow with flame to make them shoot flaming arrows by using an enchanting table. See Make an Enchantment Table in Minecraft for instructions on creating an enchantment table and using lapis lazuli to enchant items.
- You can also light an arrow by shooting it through fire or lava. So you can build a fire in front of your TNT block and shoot an arrow through it to light the arrow and detonate the TNT.
3
Use a fire charge to light the TNT. You can create a fire charge by placing a charcoal in the center of the grid, a blaze powder to the left of it, and a gunpowder below it. Fire charges are not as efficient as flint and steel, as you lose the charge that you throw.
- Throwing a fire charge at the TNT will light it. You can throw the fire charge by selecting it in your inventory and then using the item.
- Putting a fire charge in a dispenser will cause it to shoot out as a fireball when triggered. This is not as useful for TNT since the fireball shoots at a random angle.
4
Detonate TNT using another TNT explosion. TNT caught in the explosion radius of another TNT will light and explode. Unlike TNT you light, which always explodes after 4 seconds, TNT hit by an explosion will detonate after 0.5-1.5 seconds.
- Since the explosion does not produce an exact radius, make sure your TNT is well within the explosion, no more than 3 or four blocks from the original TNT.
5
Pour lava or set a fire near the TNT. If lava flows in near the TNT, it will be set off as soon as it catches fire. This can happen even if the lava is not directly touching the TNT. The same principle applies if the area around the TNT is on fire.

Part 3 of 3:

Detonating Using a Redstone Circuit

1
Gather redstone dust. Redstone dust is used to create the redstone circuit and transmit power. For a basic circuit, you can have a trail of up to 15 blocks of redstone dust. Longer trails require redstone repeaters.^{[4]

Research source}
- Redstone ore can only be found on layers 0-15, with the most abundant amount found between layers 4-13. You'll need to mine down to the bedrock layer and then begin your hunt for a redstone vein. You need an iron or diamond pickaxe to mine redstone ore.
- One block of redstone ore can be crafted into 9 piles of redstone dust. You usually get 4-5 redstone dust per redstone ore you mine.
- You can find redstone dust in dungeon chests and stronghold chests. Witches may drop redstone dust when defeated. Jungle temples spawn 15 redstone dust for the trap. They also spawn a few more for the secret chamber.
2
Make a switch mechanism. There are several different mechanisms you can use to trigger your redstone circuit:
- Button - This item is placed on the side of a full block, and provides redstone power when pushed. You can make a stone button by placing a single stone block in the center of the crafting grid. You can make a wood button by placing any wood planks in the center grid.
- Lever - A lever is placed on any solid surface, and can toggle redstone power on and off. You can make a lever by placing a stick in the center of the crafting grid and a cobblestone block underneath it.
- Pressure plate - This is a button that is pressed automatically when you stand on it. The major difference with a pressure plate versus the other two is that monsters can activate the pressure plate, making it perfect for traps. You can make a pressure plate by putting a stone or wood block in the center of the grid and an identical block to the left.
3
Create a basic circuit. Now that you have your redstone powder and a switch mechanism, you can create your basic circuit:
- Place your switch mechanism somewhere that you can use it. This will be your blasting remote, so make sure you can see the explosion.
- Place redstone powder in a trail towards where you want to put the TNT. The first piece should be adjacent to your switch mechanism. You can place redstone powder by looking at a block and right-clicking while it's equipped. Redstone ore can connect one level up or down, and the total length must be 15 blocks or less.
4
Place your TNT at the end of the redstone trail. This is where the circuit terminates, and will activate the TNT block. Make sure the TNT box is on the same level as the end of the trail, and is directly adjacent to the final redstone powder block.
5
Activate your circuit. Now that the TNT has been placed, you can activate your circuit by using the mechanism. Once you trigger the redstone circuit, the TNT will immediately be set to explode. after 4 seconds, the TNT will detonate.
6
Try a more complex circuit. By using redstone torches, you can create advanced logic gates that can remotely detonate lots of TNT at different intervals. See Make a Redstone Lamp in Minecraft for instructions on making and using redstone lamps, which are an integral part of larger redstone circuits.
- If you are new to the game, you can try it before buying it.^{[5]

Community Q&A

Question

Can I make different TNT?

Community Answer

You must have mods to do so. I vanilla Minecraft, there is only one type of TNT. If you want more, download the "Too Much TNT" mod.
Question

Do red stone rails blow up TNT?

Community Answer

No, but if you use minecarts with TNT, they will blow up when it's either activated by activator rails or when it just runs out of track.
Question

My TNT just disappears at the time it is supposed to explode. Why?

Kenny

Community Answer

If you are on a server, especially a public server, it's possible that TNT explosions have been blocked. This is usually to prevent griefing (trolling others by destroying their structures).

Warnings

Too much TNT will lag your game, so be careful. The larger the explosion, the more CPU power required, and can result in singleplayer stuttering or lots of lag in multiplayer.

It's best to stay away from TNT when it's lit. Otherwise, you may blow up.

Once TNT is primed, it cannot be unprimed and will explode.
