What is rheology? Simply put, rheology is the study of how liquids flow.

While this may seem a strange topic to study, rheology helps to explain

lots of everyday phenomena. For example:

why is that ketchup thins when you shake it, but then rethickens when you leave it to rest,

whereas yoghurt (which also thins when shaken) does NOT rethicken when left to rest? Weird right?

And then why is it that fresh cream does something completely different?

It starts off thin enough to pour, but when it's whipped it does two things.

It increases in volume, and it thickens to the point that you can pipe it onto cupcakes.

Well, in addition to explaining these everyday phenomena, rheology

also can be used to manipulate liquids. For example: it can be used to make furniture varnishes that are easy to apply,

and injections that are easy to administer, making them more comfortable for the patient and nurse. We can also

use rheological principles to reduce the frequence of injecting medicines,

for example, from once a day, to once a week or even once a month.

We'll be looking at all of this and more in future videos, but for now, you

just need to know that rheology is the study of how liquids flow,

it explains many everyday phenomena, and it can be used

in many different ways. We hope you found this video useful.
