In this Instructable, I'll show you how I opened a padlock with a ring.
Wait a minute!
This is not your usual Instructable!
Can you guess how I did it?
There is no cheating. The padlock is real and yes, I will use the ring to open it.
To make it easier to guess, I'll give you 4 clues before revealing the answer.

Step 1: Clue Nr 1
There is a very little chance that you will ever use this method in a real life situation
Step 2: Clue Nr 2
After opening the padlock with the ring, the padlock will become unusable.
Step 3: Clue Nr 3
Think about the relationship between materials of the padlock and the ring.
Step 4: Clue Nr 4
If you wear the ring for too long, it will start to melt.
Step 5: The Answer!
The padlock is mainly made from aluminium and the ring is made from gallium.
As you might know, gallium reacts with aluminium and makes it brittle.
Step 6: Making the Ring
I used a 3D printed ring a a mold.
After mixing and degassing the silicone, It was poured into the mold
Step 7: Making the Ring
I removed the plastic ring and used a syringe to inject molten gallium.
As you can see, I had 2 molds, so I made 2 rings at the same time.
Step 8: Making the Ring
I wet-sanded the ring by using an ice cold water.
Step 9: Opening the Padlock
Now when we have a ring, we can use it to open the padlock.
I scratched the padlock a little bit to expose the aluminium better.
I am not sure if it is necessary...I just wanted to make sure everything works the first time.
I used a blue tape to make sure gallium does not drip off.
After putting the ring on top of the padlock, it was melted with a lighter.
I put the padlock in the jar and left it on top of the radiator for a few days.
Step 10: Opening the Padlock
When I checked on the padlock, I noticed a broken corner and a spring.
Now you can see why I put it in the jar.
I wiped off the gallium and used my hands to break the padlock.
That's how I opened the padlock with a ring.
Obviously you will never use it in a real life and that was not the purse of this Instructable.
Hopefully this Instructable made you think......
So, How did you do?
