Haunted Padlock

There is nothing suspicious to see, just a large and heavy vintage padlock made from solid brass with the shackle open. After being locked. the padlock and key are hanging in a beautiful wood base and brass hanger. The magician asks the spectators to watch the padlock and counts down on his watch in 7 seconds (or any time you want). At the 7th second, the lock suddenly pop opens with a loud sound, even though it is completely isolated.
