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.
Bead Size. Bead size is defined as the number of rows of a given size bead that will cover one square inch. The larger the number, the smaller the bead: 14Âº beads require 14 rows of beads per inch. 10Âº beads only need 10 rows. Sizes between 10 and 20 describe seed or cut beads; numbers between 6 and 9, pony beads.
