<p>A time indicator device comprised of first and second interconnected reservoirs containing first and second liquids respectively. A first barrier is provided between said first and second liquids to prevent said liquids mixing. Said first barrier is connected via a conduit to a third reservoir containing a third liquid which is adapted to pass along said conduit over a first prede-termined time period and to effect removal of said first barrier upon contact to facilitate mixing of said first and second liquids and generation of a liquid mixture within the second reservoir of different colour to the second liquid prior to mixing and thereby pro-vide an indication of when said first predetermined time period has elapsed.</p>
