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 predetermined time period and to effect removal of said first barrier upon contact to facilitate mixing of said first and second liquid and generation of a liquid mixture within the second reservoir of different color to the second liquid prior to mixing and thereby provide an indication of when said first predetermined time period has elapsed.
