Alright, here we are again, guys! This instructable is about- wait for it- mob cannons! I can assure you that this will entertain you for a very long time, and is extremely funny. So let's get started!
Step 1: Building Your Cannon
This step is super easy. All you do is build a 3x3 square on the ground.
Step 2: Keep Building...
Next, give the cannon some height. Be careful though: if your cannon is too tall, the mobs will die when they fall in.
Step 3: Choose Your Favorite Mob!
Now it's time to choose your mob. You can do all types, but spiders and endermen will not work. I personally love pigs and villagers because of the sound they make when they are hurt.
Step 4: Fill 'er Up!
Fill the cannon with your mob until the game starts gitching out. Seriously, though. That's a lot of pigs.
Step 5: Grab Some Water
After your cannon is sufficently filled with more mobs than you can count, grab a water bucket. Put the water in the top of the cannon.
Step 6: Watch the Magic Happen... and Try Not to Die of Laughter. That Would Be Bad.
This is the cool part. Just stand back a bit.
Step 7: Collect the Bacon!!!!
Yeah. Just do it.
