Abstract:
A drinking vessel comprising a container sized and shaped so as to hold liquid therein; generating means for generating electrically generated special effects so as to enhance amusement for a user; a first switch mounted on said container so as to be operable between a first state, in which said first switch is in an electrically closed state, and a second state, in which said first switch is in an electrically open state, said first switch being in said first state when liquid is present in said container and in said second state when liquid is not present in said container; and a second switch mounted on said container so as to be operable between a third state, in which said second switch is in an electrically closed state, and a fourth state, in which said second switch is in an electrically open state, said second switch being in said third state in response to a predetermined physical activity undertaken by the user in relation to said container, said first switch and said second switch being electrically connected to said generating means such that said generating means is activated to generate the special effects only when liquid is present in said container and when the predetermined physical activity is undertaken by the user, said second switch being in said third state in response to the lifting of said container from a supporting surface, and said second switch including a mechanical switch housed in said container.
