Using a clear airline water drain 'cup' i marked upper and lower levels with a felt tip, and clamped it in a retort stand above a plastic 1 pint beer 'glass' to catch the fluid. I filled it with water and waited until the top mark was reached to start my stopwatch. The time to the second mark was 32 secs. Water has a viscosity around 0.89 (or 1) depending on the internet site. Timed again for consistency and spot on. Same test with paraffin (Kerosene) , viscosity 1.64, time 32 secs. Clearly things are not what they seem. Last desperate try with Isopropyl Alcohol, time 32 secs. Obviously the universe gods are tricksters and viscosity is just a myth !!!

OK, I think I'm stumped on this, clearly there are things going on that I have no hope of understanding.
If anyone does understands whats going on here please enlighten me - but for now I'm going to partake of a cold one to ease my addled mind.
Best Regards
