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.
Michel Tripepi / EyeEm / getty images. Clouds must have weight, because water has weight. A cloud is many, many tiny âclumpsâ of water, either liquid or frozen. The liquid droplets are about 0.002 millimetres across (smaller than the thickness of a human hair, which is about 0.050 â 0.070 millimetres). Some of these tiny droplets are so small that it would take a billion of them to make a single raindrop.
