Who says timekeeping has to be high tech? People have tracked the passage of time with sand timers for thousands of years. Did you know that these pieces were named hour glasses because it took an hour for all the sand to drop to the lower half? Early American churches would time their pastor with an hour glass; he was expected to preach until all the sand fell through. We stock sand glasses that time 3, 5, 10, 15 or 30 minutes as well as the traditional hour glass.
