Slipped

He slipped the pen off the desk and into his pocket.

The pencil slipped from the desk onto the floor.

She slipped up and revealed the surprise party to the birthday boy.

The papers slipped out of the folder and scattered across the desk.

The key slipped out of the lock and onto the ground.

The temperature slipped down as the sun began to set.

The wind slipped in intensity as the storm passed by.
