From Oil Timers, to Ooze and Time Timers, each has its own strengths in supporting people to relax or self-regulate. Oil Timers are not measured by strict time, rather they are controlled by the elements, for example on a hot day they will run faster. Ooze, one of my personal favourites for time out, runs slow, even on a hot day, it cannot be made to go faster. The Time timer has a very different role and is recommended by Autism and ADHD experts. It displays the passage of time with a disappearing coloured disk which is a powerful tool for visual thinkers of all ages and abilities.
