The answer is: a die (one of a pair of dice)

* "It's always 1 to 6" (the numbers on the faces of the die)

* "it's always 15-20" (the sum of the exposed faces when the die comes to rest after being thrown)

* "it's always 5" (the number of exposed faces when the die is at rest)

* "but it's never 21" (the sum of the exposed faces is never 21 when the die is at rest)

* "unless it's flying" (The sum of all exposed faces when the die is in the air is 21 - 1+2+3+4+5+6)
