Water beads, also known as gel beads or water crystal gel, are small spherical gels that absorb and contain a large amount of water. They are usually composed of a water-absorbing superabsorbent polymer such as polyacrylamide. Water beads can be used for various purposes such as supplying water to small animals, watering or potting plants, in vases of cut flowers, in gardens to save water, as ammunition for gel blaster toy guns, as colorful decorations or artificial snow, and as absorbent filler inside disposable diapers and sanitary napkins. However, it is important to note that water beads can be dangerous if ingested or inserted into the body. They can cause choking, internal injuries, and even death if left undetected. Water beads can grow inside the body and cause severe discomfort, vomiting, dehydration, intestinal blockages, and life-threatening injuries. Surgery may be required to remove the water beads. Water beads inserted into ears can damage ear structures, causing hearing loss and require surgery. Water beads are associated with thousands of emergency-department visits every year. Therefore, it is important to keep water beads out of reach from toddlers or anyone under the age of five. If there is any chance of a toddler getting ahold of water beads, it’s recommended to completely remove all water beads from that environment. The best way to have fun with water beads and stay as safe as possible is to maintain constant supervision and/or hand-on interaction.
