The Sand timer provides a fun and easy way to measure time. They teach the concept that time passes as sand falls between one chamber and the next.
Perfect for use in games and timing experiments. Sand Timers help sharpen concentration and ease stressful transitions in both class and at home. See at a glance how much time is remaining during a lesson, activity or therapy session with no disruptive alarm.
Virtually indestructible, including moulded end caps and thick plastic walls.
They measure 16cm tall x 7cm wide.
