Click, but do NOT drag, the orange slider to select the required time. Click again to set the time displayed. Your chosen time is shown on the timer and you can change it BEFORE you press 'start' if you want to. Click on 'Start' to set the timer going.
Sand Timer Beware! There is an audible end to the time. Enjoy! Update - oh wow, featured on 2012.11.05 I'm ridiculously happy about my "15 minutes of fame"!
