Liquid Mini Timers - Pack of 4

You simply turn them upside down and watch the two differently coloured bubbles simultaneously flow 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. Pack Size: 4 Timers in Various Colours Size: 11/5/16 cm. Usage: Visual effect Material: Plastic/Glass Weight: Approx.: 330 g. Sand timers are aesthetically pleasing ornaments, rather than accurate timepieces - please don't rely on this product for tasks requiring exact timing. * This is not a toy and is for visual entertainment only
