For the ultimate in sensory play, simply add water to this fun easy to handle jar to watch the water light up with bright colours, illuminating whatever you chose to display! Whats more, tapping on the jar rotates this through the different colour lights, providing sensory stimulation and a calming atmosphere. Designed for ease of use, these Sensory Play Jars include large, soft touch handles and have a spill proof lid, making them suitable for children as young as 18 months. Children can display and fill the jars with whatever they wish, making these great for show and tell as well as sensory play. To turn the lights off, simply turn the jar upside down nice and easy!
