Shake, swirl and twirl your way to understanding and managing your feelings with the innovative Express Your Feelings Sensory Bottles. Through their colour, fun facial expressions and the motion of their contents, each of the 4 interactive bottles in this set embodies a unique emotion. There's happy, sad, scared or angry. Happy has gold glitter, sad has a slow motion lava lamp-like effect, angry is red, and scared is green. These fun bottles give children a self-directed, tangible way to identify, understand and navigate their feelings. They are securely sealed and sized for little hands, which makes them ideal for use at home, in the classroom, in a calming corner, and on the go.
