Doctors have issued a warning over tiny beads that can expand up to 400 times their original size when exposed to liquid, amid reports linking them to serious harm and deaths among children.
The water beads are marketed for various purposes, including for use as toys, in crafting, as home decor or in floristry, and are especially popular at Christmas. They are sold under a variety of names including jelly balls, water balls, sensory beads and water crystals.
