A drinking vessel includes a container sized and shaped so as to hold liquid therein and a generating mechanism for generating electrically generated special effects so as to enhance amusement for a user. A first switch is mounted on the container so as to be operable between a first state, in which the first switch is in an electrically closed state, and a second state, in which the first switch is in an electrically open state. The first switch is in the first state when liquid is present in the container and in the second state when liquid is not present in the container. A second switch is also mounted on the container so as to be operable between a third state, in which the second switch is in an electrically closed state, and a fourth state, in which the second switch is in an electrically open state. The second switch is in the third state in response to a predetermined physical activity undertaken by the user in relation to the container. The first switch and the second switch are electrically connected to the generating mechanism such that the generating mechanism is activated to generate the special effects only when liquid is present in the container and when the predetermined physical activity is undertaken by the user.
