✔️ Trying To Crash Minecraft With Vanilla Commands! Surprising Results And Glitches!

Hey everybody, it’s UnderMyCap, and welcome back to another video. Today I’m doing something very different from what I usually do.

Normally, I make videos about commands—how to use command blocks and all that. But this time, I’m testing my PC to see if I can crash Minecraft using only vanilla commands.

Basically, I’m going to go through a bunch of steps—from exploding huge amounts of TNT to using more advanced commands—to try and crash the game. I feel like it’s going to be pretty easy, but let’s see.

Testing TNT Explosions

Starting with a 5×5

Let’s start with a 5×5. I’m going to use the /fill command and fill an area with TNT. If you want to learn more about the /fill command, I’ll put information in the description so you can learn how to use it properly.

Okay, we’ve got a 5×5 TNT setup. Let’s see how this goes. So far, so good—no crash.

Scaling Up to 10x10x10

Now I’m going to do the same thing, but make it 10x10x10. Let’s see how this goes… holy cow, it still hasn’t crashed. That’s a lot of TNT.

Trying a Massive 30×30

I think this is the biggest one I can reasonably try: around 30×30. Look at this… oh my gosh. That’s 29,791 blocks. I honestly haven’t done this before, so if this works, I’m not sure what I’ll do next to crash it.

Oh—there it goes. Oh my gosh, this is so glitchy. I can barely move. I apologize in advance if I’m shouting—I can’t really hear anything at the moment, so I feel like I’m yelling.

Now we’re into the phase where Minecraft is trying to process the movement and explosions. I actually don’t think it’s going to crash. It’s still going. Oh my gosh—honestly, it doesn’t even look like it’s done much damage yet.

There’s the destruction. I can’t hear a single thing because it’s so loud. I’m going to move away quickly.

As you can see, it still hasn’t crashed. I’m not sure if I should add even more TNT to try and force a crash, or leave it—because it’s taking so long to finish.

Oh my gosh, and I apparently completed an achievement. Is it done? Okay. As you can see, it did a lot of damage and destruction, but it didn’t crash my PC. That’s crazy.

Even More TNT (and a Long Wait)

Alright, I think this has to crash the computer. There’s no way it can handle this. This is like three times the explosion we just did, and that one took about five minutes to finish.

I’m currently frozen. It’s taken a massive chunk out of the TNT.

Now we’re at the part where it starts to “spam” the TNT, which is really weird. I’m guessing it has something to do with Minecraft’s optimization.

I’m back after ten minutes… oh my gosh, it’s still going. I’m going to end the TNT testing here, because I don’t think it’s going to crash at all, and it takes way too long to finish.

Trying to Crash Minecraft with Particles

Next, I’m going to spawn a bunch of particles and see what happens. I haven’t tested this yet, but I do know that in the past—when I’ve made videos about particles—too many particles could crash my computer. Let’s see if that still happens.

Okay, the particle command is working. No lag. I can still move properly. Nothing bad so far.

Now let’s add an extra zero. Oh my gosh, that’s a lot of particles—still no lag though, which is pretty good.

At 1,000 particles, we’re still around 60 FPS—more like 60-ish, dropping to about 57.

I’ll change it again. It looks like there’s some optimization happening—like it’s deleting particles and then putting them back in the middle of the screen.

It’s hard to look at. Oh my gosh, it looks like a sun. If I go into it, do we get any issues? No—nothing yet.

Let’s go up to 10,000 particles. That’s going to be a big jump. I can’t even look at that. That is a lot.

I’m not noticing anything too bad, but when I look directly at it, you can see the frames dropping a bit.

Alright—another zero. Let’s see if this does anything…

Oh. Okay. I think we just did it. Wait—can we still move? No. I think we actually just did it.

Particles are probably one of the easiest ways to crash Minecraft. I can’t believe it—yeah, we crashed.

Summoning Too Many Mobs

Now let’s go to the next test. I’m going to create another world—I’m not going back into that one. Okay, everything is working again.

The next command: /summon. I’m going to summon a whole bunch of animals and see if it crashes. Let’s start with pigs.

Okay, we’ve started. Nothing bad yet—just a lot of pigs.

Oh my gosh, Minecraft is doing a pretty good job handling this. I haven’t noticed them dying—except for some of them dying on the cactuses.

Honestly, I’m really surprised. On my last computer, this probably wouldn’t have been able to handle it.

I am noticing something though: when I look at the pigs, the frames drop a bit. When I look away over here, it’s kind of fine. I think I’m about to start pushing it.

Oh—okay, that’s loud. They all seem to be trying to run away.

Let’s change the mob to something else… oh my gosh, this is too loud. I’m turning the volume down—hopefully that helps.

It’s super laggy now. I think we’re about to crash. I can still hear the noises, though.

As soon as I turn around and look over here… yep. I think we crashed.

It crashed. Holy—wait, that’s so weird. It did crash. Wow.

So if you spawn too many mobs, that’s another thing that can crash Minecraft.

Other Commands That Can Break Things

No, no—don’t open that world again. Don’t open that. No.

The last few things I can think of are commands like teleporting everything to you.

Let’s see… holy cow. Oh my gosh, there’s a full-on fight happening.

Let’s try that again. Look—there are the minecarts. I think I’ve broken Minecraft. I don’t know what’s happening. I’m just going to keep doing it.

One more time… okay, nothing. Nope—nothing like that. That’s good.

Actually, not good—we want to lag it out.

Playing Sounds

Next test: /playsound. Let’s see if that does anything.

That’s just incredibly annoying. Nothing’s happening.

Clone Command Glitch

The last one I can think of is using /clone.

Oh! It did something. It’s lagging. Oh, it’s definitely doing something. It made a weird “step” shape. It’s actually working.

What happens if I try and break this? I think it’s breaking a bunch of blocks and replacing them with the same blocks.

Okay, yeah—this has definitely glitched my Minecraft.

I can’t actually get out. I’m stuck on this thing here.

Yep, it has frozen again—and it crashed.
