Explain Like I'm 5 (ELI5)
Objective and layman-
ELI5: How does a text through iMessage reach another’s phone halfway across the world in seconds?
I’m in California and I was texting my brother in the Middle East with no delay (both using iMessage.)
How is this possible?
ELIF: How do lumens work when measuring brightness of flashlights? Ie. How do cheap flashlights have outputs of like 2000 lumens?
ELI5: What exactly is a watershed and how does it work? For instance, we live in the Chesapeake Bay Watershed area. I have attempted to read on the subject, and consider myself a smart gal, but this just confuses me all day.
ELI5: Why do tea bags say ‘Do Not Microwave’?
Does it have to do with how the tea steeps? Or something with metal staples on the bag?
