THIS IS SO UPSETTING
Oooh, I saw this in a Vsauce video! This is called Lahaina Noon and it literally only happens in Hawaii, a couple of times a year around late spring and early summer, generally in May and June.
The even has led to this sculpture, called Sky Gate, by Isamu Noguchi
which, during Lahaina Noon, casts a shadow
that is perfectly circular.
