Oh yeah, I'd forgotten how weird smell in particular was. I seem to remember at the time that there were three competing theories for how smells are even perceived or what gives a substance a particular kind of smell, and each only explained a subset of smells.
For the helium leak, is one symptom a high squeaky voice, or is that at already really dangerous concentrations?
- guitarbill 8y agoFrom what I remember, dizziness, headache, inability to concentrate, etc. You'd notice a big/quick release as the liquid helium boils of quite easily. A slow leak is more dangerous, in which case you might even get used to the higher pitch without noticing.
- fwip 8y agoOne symptom of a helium leak is that your iPhone might stop working: https://motherboard.vice.com/en_us/article/gye4aw/why-a-helium-leak-disabled-every-iphone-in-a-medical-facility https://motherboard.vice.com/en_us/article/gye4aw/why-a-heli... This happened also to the coworkers of a friend of mi e - occasionally everyone's iPhone in their office would stop working. Android phones still worked fine. Later (after this article was published) they found out there was an MRI machine downstairs.
