Liquid Timer Double
You simply turn them upside down and watch the two differently coloured bubbles simultaneously move to the bottom of the tube. The liquid timer double takes approx 1 min to run through. Please note these timers are for sensory calming and not for accurate time management. The action of the liquid showers can stimulate visual learning with regards to colours and the passing of time. This sensory activity is praised as a fun and stimulating early years resource for younger children. Advisory note: Liquid timers are filled with mineral oil, please take care as staining may occur if broken which in many cases can be removed with detergent and water. We recommend placing on a coaster or mat as a precaution. One Liquid Motion Timer is supplied.
