Explain Like I'm 5 (ELI5)
Objective and layman-
ELI5: Why are some smells stronger than others? E.g. With the same ammount of rotten egg and lavender the rotten egg would be alot more pungent
ELI5: Why do stars twinkle while planets don’t?
Also, why do some faint stars seem to disappear when we look directly at them, but can be noticed when we look at a nearby patch of sky?
