You want to see weird water look up super critical boilers. That stuff was nasty. A regular steam leak will set things on fire. That stuff would explode a broom. We looked for the leaks with straw brooms. You can’t see steam in normal conditions. Only its effects.
Blech, I’ve heard stories in my industrial automation days of people being clipped by invisible high pressure steam leaks. No frickin thank you, regular stovetop steam jacks me up frequently enough.
Well, now this is on my list of invisible things that scare me:
- Radiation
- Methanol fires
- Supercritical steam jets
Not quite invisible but you could also splash and wade into a pool of strong acid thinking it was water, during what first seemed like a somewhat routine FUBAR maintenance situation…filling your boots etc.
