How to raise viscosity of water

Question

I need to measure a machine for a liquid of which I know the viscosity (89 Kinetic Viscosity) but I don't have the liquid at hand. Is there a clever way of increasing viscosity of water to 89?

Answer 1

There are a whole class of chemicals called thickening agents used in the processed food industry which when dissolved in water, increase its viscosity. Some are used to thicken liquid foods so people who have difficulty swallowing can consume them; these are available in drug stores.
