The ability to gather viscosity data on a material gives manufacturers an important information about “product dimension”.
This data it’s necessary to predict how the material will perform in the real world.
For example, if toothpaste does not have the correct viscosity, it can either be too difficult to squeeze out from the tube, or we could squeeze out too much.
Knowing the viscosity of a material/product is also necessary to design correct packaging and provide relevant transportation.
That is just a very simply explanation about the importance of viscosity measurements and if you are a future scientist and you are back at school this week to learn more we wish you a fantastic school year and lots of new discoveries:-)
