Video Summary
AI GeneratedThe creator showcases seven LEGO safes of increasing complexity, ranging from a simple hidden compartment to a high-security vault. The video demonstrates the cracking process for each safe, reveals the internal Technic mechanisms used to lock and unlock them, and highlights various creative building techniques.
I've built the 7 most secure LEGO safes, starting from a noob safe all the way up to a safe
with a pile of money inside.
But here's the problem.
I only have 10 minutes to crack them all, otherwise they'll lock up.
Let's start with this noob safe.
And there are no holes here.
Ah well, that makes sense.
The noob just hid the money under these pieces and that's the whole point of this safe.
I built the next safe 6 years ago and it still works.
There's even something else inside.
If you turn the safe around, we won't see anything from these sides because the entire
mechanism is on the front, specifically on this door, which is currently locked.
I'll try turning this piece right here, but nothing seems to be happening.
The second piece.
Oh look, something is starting to move.
We turn it like this and the safe is open.
And inside, inside there's only 200 bucks.
Alright, let's take a look at the mechanism.
I made this mechanism using only 7 Technic pieces.
The rest here are just regular bricks.
Right now, the safe is locked because the green piece is blocked by the grey wall.
And for it not to get in the way, you need to turn it in the right direction.
Now the safe opens, we close it, turn it back and the safe is locked.
But let's make a deal.
I will continue showing the mechanisms of these safes if you give this video a like
right now.
Did you like it?
Now let's move on to the next red safe.
And it's made in the shape of a 1x1 piece.
I think it turned out looking similar.
But listen, I don't see any holes here where you'd need to insert some kind of key.
The only thing is, there's something inside this little hole, but the solution definitely
isn't that.
Wow, look here, it turns out there's a sliding part.
Okay, let's open it.
And here are the insides of the safe.
Money is stored inside.
And yes, the safe is open.
Here are our 400 bucks.
By the way, you can put a lot of things in here.
I can even put my minifigure in and close this safe.
There is no mechanism inside the safe itself.
Its only principle is a hidden door and the hope that a thief won't figure out how this
safe opens.
I call the next safe the smallest one because it only has 50 parts inside.
Even though it's small, it's locked very tightly, the handle even falls off.
To break into it, I've prepared the first key, the second key and the third key.
Let's start with the first one.
This is the red key and I think it should fit perfectly here.
Yes, look, it goes into this hole.
Well, now the safe should probably be open.
But no, the safe is locked, the key didn't help.
The next key is yellow, just like the color of the safe and I think it should fit.
We insert it inside like this.
But no, it won't go any further and the key broke on me.
Alright, apparently, the only hope left is the last Phillips head one.
And this is strange.
The hole here is round but the Phillips head key fits.
So is something moving or not moving?
Oh look, the safe is opening.
Although there was only a hundred bucks inside.
Well, okay, at least we were able to crack this safe.
And here by the way is the mechanism itself.
It's actually really big in there.
I had to buy the parts for this safe on the bricksmarket.ru website because it uses Technic
parts, which to be honest, I didn't have enough of so I had to order them.
Right now, the safe is locked because the black parts are preventing it from opening.
When we insert the correct key and turn it upwards like this, the parts lift up and accordingly
the safe is open and you can hide something inside.
And by the way, on Bricks Market, besides Technic parts, there are also regular bricks
like the ones here, electronics so your mechanisms can work and of course, firing cannons.
The next safe can be called magical and it knows how to steal money.
I open, let's say, the top drawer.
I take, for example, two coins.
By the way, write in the comments what kind of money this is.
I drop the first one, I drop the second one and in theory, the money should be saved in
there.
But when I press it, I hear the money jingling.
We open it and it's empty in here.
How is that possible?
On the side, I specifically left a window to show how it actually works.
We take two coins, put them in the safe, then close it and they fall down because the bottom
of this safe isn't real.
I have a separate long key designed for this safe.
But for example, I'll try to open this safe with the old key.
I insert it here and it just pops right out.
But when I insert the correct key, I can open all the locks.
The first lock, the second lock and now the safe should open.
Yes, it all opens.
Then here's our money that was hidden in there.
Making a safe like this is actually not difficult.
The main thing is to have technique parts.
This is what the bottom of the top drawer looks like.
It seems to us like these are ordinary black tiles.
But in reality, they are technique parts that drop down when we push it inside.
When we pull it out, the bottom rises, creating the illusion that everything is actually fine.
Although this safe can actually steal your money.
But let's take a look at the next safe.
We don't have much time left and this safe has four levels of protection.
But besides it, I also have a safe for the military.
In this crate, the military stores secret weapons that need to be protected.
But the two of them can't handle it alone.
That's why I'm sending a huge military shipping container to help, which has doors that open
like this.
And there's a lot of equipment inside.
Wait though, this container can also open upwards like this.
Wow, how much weaponry is inside there?
For extra protection, I'll put up a fence.
The enemy definitely won't get past this barbed wire fence.
These are just new sets from my MLS store minifigure shop.
Here's the military container and here's the large military set.
And this is the fence with barbed wire.
September 1st is coming soon, so you definitely need a new backpack from my channel MLS Production
just for LEGO fans.
By the way, there are hidden secret pockets here.
The backpacks are already on the website as well as a huge selection of minifigures via
the link in the description.
However, let's get back to the safe.
As I said, there are four levels of protection here, or more precisely, four buttons.
This is a sliding part that is currently locked and it won't open.
So let's try to guess the combination.
For example, like this.
Like this, like this, like this, like this.
Let's check.
No, the safe is locked.
Let's press here, here, here.
The safe is still locked.
And if I press the one and only correct button, this one, then the safe, no, it's locked.
Wait a second.
What if I press here?
There.
Actually, I mixed up which button was the correct one.
And now the safe opens.
It's empty inside, but you can put something in there.
Inside I'm going to store a hundred LEGO bucks.
I'll close it and press the wrong button, for example, this one.
That's it.
The safe is locked.
Inside, the safe's mechanism looks very complicated, but that's just at first glance, of course.
Although building a safe like this is actually not easy, it would take, well, at least 30 minutes.
Look, there are four buttons here that we can all press.
There's also a white rubber band stretched here, which returns the button to its original
position after we press it.
Each button has a bevel at the bottom.
It's needed to press against another bevel, so when we press it, this bottom part blocks
the sliding section of the safe.
Then when we press the top button, this one here, I can move it with my hand.
Then the safe opens and we get access to our LEGO money.
Then we close the safe back up and press the wrong button, for example, this one.
That's it.
The safe is locked from the inside.
By the way, in real life, they actually make locks with the same mechanisms.
So for the sake of this safe, you definitely should hit the like button on this video right
now.
And now, the most complex and the biggest LEGO safe that exists.
Many people wrote in the comments that it's easy to throw the safe on the floor and it
will break.
That won't work with this safe.
Just look at how thick the walls are here.
Yes, it certainly won't withstand a blow from a hammer or a sledgehammer, but it will
100% survive a fall to the floor.
And to open it, I need to enter the correct combination of these colors.
Green, blue, yellow, red.
So first I need to rotate the green color like this.
Then we return the red one to the blue one's place and instead of the red one, we need
to put the green one.
Oh, the door is almost open.
This means we've almost unlocked the safe.
Turning it like this and the door opens.
And inside this safe, ta-da, are my two favorite figures from my shop.
It's the transparent figure and the golden figure.
