I have to do a science fair project and need to measure the viscosity of chocolate syrup when it is cooled. Any ideas how I can measure the viscosity, I'm really clueless on this?

viscosity is a force of resistance, so it is measred in force units, called dynes. It can be measures with a device that spins in the liquid and measures the force of resistance.

Last semester I did a lab similar to yours where I measured the viscosities of different biofuels. I set up 2 large, 800 mL beakers, full of tap water. I used 2 different temperatures, one cold (around 0 celsius) and one warm (around 40 celsius). We clamped a viscometer so it was hanging inside the beaker, but the open ends above the water. Then we injected the fuel into the viscometer to measure the viscosity. Hope this helps!

With due respect, Reb has it wrong. Viscosity has units of poise or the gram-cm/sec, and for liquids like water, the centipoise is used. A second dimension of this project is whether the chocolate syrup is a Newtonian liquid. The method described is correct.

I think you can buy a viscosity cup and check it that way. That would be least expensive way.
