The viscosity of a fluid is basically a measure of how sticky it is. Water has a fairly low viscosity; things like shampoo or syrup have higher viscosities. Viscosity also depends on temperature: engine oil, for instance, is much less viscous at high temperatures than it is in a cold engine in the middle of winter.
One small packet of 7 grams will produce about 500 grams of beads once they are hydrated. Soak overnight to a ratio of one packet of beads to 50 parts water. You can add more water or pour out any extra water when the beads expand. They can also be used to water potted/garden plants and flowers.
A â Add a package of the dry beads to a 1 quart bottle of water. Let it stand for about four hours (overnight is great). The beads will swell up and increase their weight by approximately 50 times. Next, use a sieve to strain off any surplus water. Now you have a large bowl or vase of sparkling water beads.
