✔️ 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 to what I usually do. I normally create videos about commands and how to use command blocks, but this time I decided to do something a little different — I’m testing out my PC and trying to see if I can actually crash Minecraft using only vanilla commands. If you’d prefer to watch the full video, you can check it out here: Watch on YouTube.

The Challenge

The idea is simple — I’m going to go through a whole bunch of steps, from exploding massive amounts of TNT to using advanced commands, to try and crash Minecraft. Honestly, going into it I thought it was going to be pretty easy, but the results were genuinely surprising!

Step 1: TNT Explosions With the Fill Command

The first thing I tried was using the fill command to place and detonate TNT. I started off with a 5×5 area and worked my way up. If you’d like to learn more about how the fill command works, I’ve included some resources in the video description. The 5×5 went off without a hitch, so I stepped it up to a 10x10x10 — still no crash, which was already pretty impressive! I then pushed it to a 30×30 area, which came to a massive 29,791 blocks of TNT. I honestly hadn’t tried anything like this before, and the explosion was absolutely wild. The game became incredibly loud and glitchy, movement became nearly impossible, and it took a good five minutes for everything to finish exploding. Despite all of that chaos, Minecraft did not crash. I even earned an achievement in the middle of it all! I decided to leave the TNT testing there because it was clear it wasn’t going to bring the game down on its own.

Step 2: Spawning Massive Amounts of Particles

Next up, I tried spawning in a huge number of particles using commands. I knew from past experience that too many particles had caused crashes before, so I was curious to see how my setup would handle it this time. Starting small, there was no lag at all — things were running smoothly. I kept adding a zero to the particle count, pushing it to 1,000, then 10,000, and the frames held up surprisingly well, sitting around a solid 60 FPS. It did seem like Minecraft was optimising things by deleting and respawning particles in the centre of the screen. However, once I pushed it up to 100,000 particles, the game completely froze. We couldn’t move, and sure enough — it crashed. Particles turned out to be one of the most effective ways to bring Minecraft down!

Step 3: Summoning Mobs With the Summon Command

After creating a fresh world, I moved on to using the summon command to spawn in as many animals as possible. Starting with pigs, the game handled it surprisingly well for a while — the pigs were spreading out, some were dying on cacti, and the frames only dropped noticeably when I was looking directly at the mob crowd. I then switched to a louder and more chaotic mob type, and things escalated quickly. The noise alone was overwhelming, and the lag became severe. Sure enough, it crashed. So spawning too many mobs is absolutely another reliable way to crash Minecraft!

Step 4: Teleporting Everything and Playing Sounds

I also experimented with teleporting everything to my location at once, which caused some wonderfully bizarre results — minecarts appeared out of nowhere, mobs started fighting each other, and the game looked completely broken. Repeatedly running the command didn’t seem to cause a crash on its own though. I also tried the play sound command, which was incredibly annoying but ultimately didn’t cause any issues performance-wise.

Step 5: The Clone Command

The last command I tested was the clone command, which clones a section of blocks and places them somewhere else. This one produced some fascinating and strange results almost immediately. It started creating weird step-like structures, breaking and replacing blocks rapidly, and before long the game had completely glitched out. I found myself stuck and unable to move, and then — you guessed it — it crashed again. The clone command is definitely one to watch out for if you’re pushing the limits!

Final Thoughts

Overall, this was such a fun experiment and the results were genuinely surprising. Minecraft held up far better than I expected in some areas, especially with the TNT, but particles and mob spawning proved to be real weak points. The clone command also turned out to be a fantastic way to glitch and eventually crash the game. It just goes to show how much Minecraft’s optimisation has improved, while also highlighting where its limits still lie. I hope you enjoyed coming along for the ride — it was a wild one!
