Water gel (plain)
Water crystal gel or water beads or gel beads is any gel which absorbs and contains a large amount of water. Water gel is usually in spherical form and composed of a water-absorbing superabsorbent polymer (SAP, also known as slush powder in dry form) such as a polyacrylamide (frequently Sodium polyacrylate).
Hydrated water gel, or water beads

Water gels are used for:
- Supplying water to small animals as an alternative to supplying water in a dish. Some small animals tend to fall into dishes of water and drown.[1]
- Watering or potting plants.[2]
