What's up everybody!
Welcome back to my laboratory where safety is number one priority,
and today we're going to put to the test Master Lock security 3, and Master Lock security level 4.
Security 3, level 3, and security level 4.
They're mostly used for the lockers in school or the gym,
nothing that you will lock overnight where there is no people,
and I'll show you why you don't want to use it on a garage or something you don't attend,
or, like, lock it for very long time.
They're just really easy to hack into.
So today we're going to open these locks with a torch.
Okay -- Master Locks -- let's put it to the test.
Let's light it up with a torch and let's see if it's actually going to survive.
Boom. You see? It opened.
[In] about under a minute, that lock completely burned out... inside of it.
And all I used is a little hand-held torch, so anybody can get it.
It's cheap and easy. So, that was easy to melt into.
I wouldn't touch this part, it's super, super hot.
Check this out -- all that melted metal from the lock.
Super easy to open it with the torch. Quiet and easy... wow.
So combination lock was security rated 3,
but this time we're going to do security rated 4, a step higher.
Let's see what it will do. I think it will melt just as easy, maybe even easier.
Let's check this out. Security rating four.
Oops.
Let's see how hard it is to break the key inside of this lock.
So, easy to open it with the key, but if you twist it the wrong way...
look how easy it is to break that key.
Now my key is broken to open this,
how do we open this key super simple without making too much noise and breaking other stuff?
Wow, the whole lock is set on fire... this is crazy.
Can you even see?
Look at this.
Crazy! This is a flame ball.
Wow, security 4 is not melting as easily.
Boom. Whole lock just fell off.
Crazy, huh? Wow!
Look at this. It just melted off,
all that metal... super, super hot.
So this is the only piece that [we] have left from that other security 4 lock.
It completely melted all the way.
This is it right here.
Security 3 lock only melted from the inside.
You be the judge which lock is stronger.
Check this out, this is what [we] have left from this lock, the second lock.
Pretty insane, right?
Completely melted. Under a minute.
By the way, this is super, super hot.
This is why I'm wearing welding gloves.
