Nutty nut

It shows a nut, a bolt, a small plastic sleeve, and a small container with a lid. The threaded part of the bolt is pushed through the sleeve. The nut is placed on the bolt and screwed tight. The screwed-on nut is then placed in the container and covered with the lid. The container is shaken for a while. The rattling sound of the nut is heard. Then the lid is removed.
