disappear into thin air

Leave no trace

To disappear into thin air is to vanish completely and mysteriously, leaving no trace or explanation: The documents disappeared into thin air.

The phrase emphasizes the baffling nature of the disappearance—as if someone or something evaporated into nothing.

Often used when things go missing under puzzling circumstances: My keys have disappeared into thin air.
