A simple experimental setup can be used to demonstrate the storage of macroscopic dust particles in a ‘‘Paul trap.’’ The trap is operated at atmospheric pressure, which results in an efficient ‘‘cooling’’ of the stored particles. Under these conditions, a single anthracene dust particle has been confined for over 2 months. The device is well suited to show the formation of ordered structures when a number of ‘‘cooled’’ species are trapped. Due to its overall simplicity, the setup can be used in lectures, student laboratories, etc.
