Thank you very much for your response.
If I understood the article you referred to, temperature would be another way to modify the viscosity of water. (Water viscosity at 0 C is about 6 times what it is at 100 C). Also, I was hoping to keep the water looking like, well, water. A mixture that resembles corn starch (while fun) is not what I had hoped for. While quite possibly unrelated.. I was hoping for something more akin to adding salt to water to lower freezing point and raise the boiling point, while still having it "look" like water. Thanks again for your insight.
