Minecraft Monster Slaying: How to Drown Your Enemies with a High-Suction Moat

Minecraft just wouldn't be the same without all of those pesky monsters trying to break into your house and jump on you until you die. But that gets tiring after awhile, and sometimes you just want a safe place to go where you don't have to worry about being eaten, shot, or blown up.

Here's your home. Isn't it nice?

Don't you want to protect it from monsters while also looting their items?

That's where this build comes in! You can protect any area that you'd like, and no extra effort is required. This drowning trap will work nonstop, 24/7, to make sure that your home or workspace stays monster-free. The best part is that all you need is a bucket!

This is what it will look like when finished:

Now let's get started...

Step 1 Dig a hole

Dig a hole 1 block wide around your house, completely flush with it. I made this one 6 blocks deep, but the absolute minimum is a mere 3 blocks!

Step 2 Add a ledge

Skim off the edge of your hole so that you have a single step before the drop.

Step 3 Jump into your hole and break blocks!

Now get down into your hole, and destroy all the blocks underneath your home or building to a minimum of 2 blocks high. You could also make it higher if you like more headroom. 

You may find it helpful at this stage to build a ladder going up into your home, so that it's easy to get back out.

Step 4 Add some blocks!

Now go underneath your house and add one row of blocks coming down from the ceiling at its edge (or more than one, if you made your ceiling higher). The important part is that there's an empty space between the blocks and the floor. I recommend using glass so that you can see through it, but using any other block doesn't affect this trap's functionality.

Step 5 Make a ring!

Now you're going to dig a 1-block-deep square just inside your perimeter.

Step 6 Just add water!

All that's left to do is add water! Remember that 1-block-wide ledge that we added at the top? You're going to use your bucket to add water to every single space along that ledge, so that from every single block, the water is toward your house and not sideways.

If you've done this correctly, any mobs who attempt to attack your house will step in the water and instantly be pulled forward and down into the depths. The force of water will hold them down, and they'll suffocate!

This is what it looks like from inside:

The monsters are too tall to fit through the 1-block-high empty space, but the water flows right through it and the pressure pushes them against the glass until they drown! Once they have drowned, any items they drop will float right along with the water and be deposited underneath your house, ripe for the picking.

Voilà! No muss, no fuss, no monsters!
