Hydrargyrum

It all went downhill when I volunteered to make breakfast before going to work on a Saturday for Master Shifu and The Dragon Warrior. You get fast training, your brain is being blown dry by the two master's thinking and you end up processing samples.
So I've been doing voltametry.
You're watching my waste bottle. Think back about those chemistry practical with saline bridges. Well, same as but using mercury as an electrode.
Since it's hazardous to breathe mercury fumes. We store the spent mercury (has oxides fixed on it, gives it a tarnished look) with water or samples.

On a totally separate subject, turned my hair blue.
