One day I had my phone charging on the same table I was measuring a liquid from two glass dropper bottles. The phone heard me shaking the bottles, clinking the glass pipettes, and dropping the liquid into water. I’ve never ever talked about dropper bottles as I didn’t know what they are called before this incident. I had bought the liquids with their bottles about a month before, and I’ve only ever referred to them by the brand name of the liquid.

My Quora feed 20 minutes later:
“What are the advantages of using dropper bottles in chemical processes?”

A phone can notice when it’s in the hands of a security expert and start acting normal. Before dieselgate, Volkswagen cars had been emissions tested for years without finding anything suspicious. Turned out VW used the car’s sensors to detect when it was being tested.
