Liquid Timers S Shape - 3 Colours - One Supplied

You simply turn them upside down and watch the two differently coloured bubbles simultaneously walk down the staircase to the bottom of the tube. The liquid timer 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.
