the supplies you'll need

- 1 standard padlock

-2 cans of compressed air
the kind used to blow the dust out of you computer

-1 hammer

Step 2: Attach you lock to a secure latch

Picture of Attach you lock to a secure latch
Insure that your lock is attached to a secure latch as we'll be striking it with a hammer.

Step 3: Spray the lock with the compressed air

Picture of Spray the lock with the compressed air
First, turn the air canister upside down and begin to spray the lock. By turning it upside down you're actually spraying 1,1,1-Trifluoroethane which cools the metal lock to -67 degrees fahrenheit! Frost will immediately begin to from on and around the lock.

Step 4: Strike the lock with a hammer

When the compressed air cans are empty, very carefully and very forcefully strike the lock with a hammer. The lock should either shatter off the post completely , or fracture around the post!

Congratulations! You've smashed off a frozen lock!

Does anyone know if this would work if instead of using a hammer, you simply put a blow torch to it immediately? I think that it would crack but I'm not sure.
Use a rock to hit the frozen lock, because it is small and easy to carry.

dont look at it being easy to carry..... its dirt cheap and you can find it anywhere!!!!

A rock? Isn't there a waiting period for those now?
(You might have to carry the rock concealed, and that means you have to register your rock!)
wont it melt to fast for you to strike effectively.
true but you will have to deal with the poisonous air that comes from spraying it upside down.

You broke the lock in half after removing it from the tool box? But this scene is cut? Am I paying too much attention?

Macgyver! Oh yeah!
I really hope this works! My non-custodial parent rammed my car in traffic, then chased me out of it and stole it. He has it chained up at his house, and for some reason the police won't help me, Hopefully I can freeze the lock and get my car back!

also make sure its on a secure latch if you wanna break someone else's lock, you wouldnt want to waste time and some spray when eventually the whole thing comes down with the lock, woukld you? :P
the bomb squad uses this idea for detonating bombs they also use water jets too. But no BOOM! when they freese the bomb :(

I cant believe that ,that is compressed air and with 1 screwdriver an 1 hammer i have "opened " locks with 1 (one, Blow)--so i cant see the point unless someone uses liquid nitrogen.............................
They dont just use compressed air, it is co2 which makes it the temp that is is the can of air is just like a co2 fire extinguisher but correct me if im wrong
mythbusters is testing this tonite and they said the lock has to be frozen for like 5 mins so this is better

Why wouldnt you just cut down the place where the padlock is on with metal scissors? or just get a key and open it nicely (im sure they dont make much of different keys for these padlock :D) but well its for educational purposes only so yea its kinda nice 5\5

Na, this looks much more fun. I seriously doubt that any key will do. Metal scissors? You mean...they make scissors out of stuff....other than metal?!? I want a pair of cardboard scissors! Then I can lop off paper locks and demolish Japanese houses and give people third degree paper cuts.

also it is very more quiet than using power tools
cause this is way faster and requires smaller and easily accessible materials.
nice saw the idea on call of duty 4 second from last mission got me thinking if you could actually do it. cheers good post

Jeez dude, you must've gave that lock more whacks than Lizzie Borden's parents received -- combined. Poor lock, how could you! It just wanted to help you keep your tools safe and you beat it to death!
lol i have no idea wat u said or who is lizzie borden but that just sounded funny as hell
A psychotic red-head who off'd her parents. There's a Rhyme regarding her --

Lizzie Borden took an axe
And gave her mother forty whacks.
And when she saw what she had done
She gave her father forty-one.

Who HASN'T heard of her? Besides him....
Her stepmother suffered 18 or 19 blows, her father 11.

The bpt for 1,1,1,TCE is -47C, not -67C, and that temperature wouldn't be maintained for more than a few moments after cooling. What temperature does steel become brittle below, anyway?
