ABSTRACT:
A viewing device includes a housing defining an interior chamber through which light can pass. The housing includes first and second spaced apart openings communicating with the interior chamber such that light entering the first opening is viewed by a user looking into the second opening. The second opening is further configured to receive sound created by the user and the housing is configured to transmit the sound entering the second opening toward a sound exit location of the housing at or near the first opening. The second opening can define an eyepiece portion into which the user looks and a mouthpiece portion into which a user speaks. The viewing device can take the form of a periscope toy.
