Water crystal gel
(Redirected from Water beads)
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).
Uses
[edit]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.[citation needed]
- Watering or potting plants.[1]
- In vases of cut flowers
- Use in gardens to save water.
- Used as ammunition for gel blaster toy guns. Usually came in 7–8 mm when full size.
- Colorful decorations or artificial snow.[2]
- In a dry state as absorbent filler inside disposable diapers and sanitary napkins.
- Proposed for controlling or containing floods.[3]
