The moment I saw the golden-looking lens orbs I knew it must be the neutrino detector. Cool stuff, I didn't realize there were multiple such facilities

I'd like more info about how ultra pure water dissolves metal... they kind of just threw that out there (5:17) and then moved on immediately

I think it just means that ultra pure water has a higher potential to dissolve minerals, albeit at a very slow rate, as it isn't saturated with electrolytes yet. It's just that pure water will absorb (or "dissolve") metal electrolytes like magnesium, sodium or potassium more quickly than water already rich in minerals.

### How Ultra Pure Water Dissolves Metal
Ultra pure water, also known as Type 1 Water, is a highly purified form of water used in various scientific applications due to its exceptional purity levels. This water is so pure that it contains only H2O molecules and hydrogen and hydroxyl ions in equilibrium, making it almost like an insulator compared to other substances. The resistivity of ultra pure water is extremely high, at 18.2 mega ohms, which, combined with the absence of minerals, makes it unsuitable for consumption as it can strip important electrolytes from cells.
#### Corrosiveness of Ultra Pure Water
Contrary to its neutral nature, ultra pure water can exhibit corrosive properties when in contact with impurities and minerals. Water at such high purity levels tends to absorb impurities and minerals into its structure when exposed to them. This unique characteristic makes ultra pure water capable of dissolving metals due to its aggressive nature when interacting with substances.
In scientific applications like chromatography and trace analysis, the use of ultra pure water is crucial to ensure accurate and reliable results by eliminating any interference from contaminants. The production of ultra pure water involves a meticulous process of purification through multiple stages to achieve the desired level of purity, often reaching parts per trillion levels of contaminants.
In summary, the exceptional purity of ultra pure water makes it a valuable reagent in scientific settings; however, its corrosive nature when in contact with impurities allows it to dissolve metals effectively.
