Viscosity: A Property of Fluids

Viscosity is the term for the resistance that a fluid has to flowing and movement.

An instrument that measures viscosity is called a viscometer.

--------------------------------------------------------------------------------------------
Experiment:

-Fill a small clear plastic bottle with a tight-fitting lid with corn syrup, leaving a 3-cm space at the top.
-Fill another with water, leaving a 3-cm space at the top.
-Add a small identical amount of paper confetti to each bottle.
-Fasten the lids securely.

And I think your supposed to shake the bottle or something.
--------------------------------------------------------------------------------------------

Anyone knows what happens? I don't have any corn syrup right now, so unfortunately I cant do it.

And can someone explain to me what the Scientific Method is and the steps to the Scientific Method?

Any good help will be greatly appreciated, and I mean it. I will also rep you.

Man, if your lab was more on viscosity than on anything else I could've helped you a lot. I'm studying fluid mechanics and hydraulics in college right now.

Once you do your experiment let me know what happens and I'll try to give you a little help if you want it.

As for the scientific method, just google it. Pretty straightforward.

Ive got the Scientific Method now:

Prediction, Hypothesis, Experiment, Observation, Conclusion.

The problem is, I don't have corn syrup in the kitchen right now. Thats why Im asking for everyone that is good in science for their input on what happens to paper confetti when its shaked up in a water bottle filled with corn syrup.

Use honey.

Hmm...i don't think you're supposed to shake it. Once you add the confetti, see which one sinks the fastest. Obviously it's going to sink faster in water because water is thinner, so you know water has less/higher viscosity. (I sort of forgot how to use the term, but I'm pretty sure the whole point is to see whether water or corn syrup has a higher viscosity.)

So, the confetti will sink faster in water than in corn syrup?

[Diable]

I don't believe it would sink at all.If a liquid has a high enough viscosity then
a ball bearing would probably float on it.

usually if u wanna measure viscosity u'd pour things out to measure how fast the liquid is moving. in this case, corn syrup would b more viscous because of the high intermolecular forces between them. yes, water does have hydrogen bonding, but i think there is something in corn syrup that makes it extremely viscous.

im not sure wat ur experiment is for, but if its to test which one is more viscous than the other, then having confetti in it wouldnt do anything. the reason is cause viscosity is measured on resistance of FLUID movement, and confetti isnt a fluid substance.

Here's my take:

Viscosity is the resistance of a fluid to deform under an applied stress, not necessarily the resistance to move. But if you want to look at it as a resistance to flow, think of it this way: In order for an object to move through a fluid, there must be flow within the fluid itself, even if the entire mass of the fluid is not moving anywhere. Molecules move out of the way to accomodate the falling object, and molecules replace the space where the falling object was. When a fluid is very viscous, there are stronger interactions between its molecules. and it's harder to move them out of the way.

So the time taken for confetti to fall through a fluid is a measure of viscosity, as long as the confetti is dense enough to sink in both water and corn syrup.

That's the experiment you have to do? I think we looked at the speed of liquid travel down a sloped sheet of glass, back in high school science class.

iight thanks for the help.
