Does a teaspoon in the spout of an opened bottle of sparkling wine keep it fizzy?

Does a teaspoon in the spout of an opened bottle of sparkling wine keep it fizzy?. The long-running series in which readers answer other readers’ questions on subjects ranging from trivial flights of fancy to profound scientific and philosophical concepts
