Amazon, Target and Walmart, three major US retailers, will stop selling water beads due to safety concerns. This comes after reports of injuries and deaths in children who swallowed or placed them in body openings. While water beads may seem harmless, they can expand to the size of tennis balls when exposed to liquids, up to 1500 times their original size. This poses choking and blockage hazards. All three retailers confirmed they will remove water bead products marketed to or accessible by children from both physical stores and online marketplaces.
