You know what? We used to shop road asphalt, tar or that, or Taiwanese say "point earners glue" was in fact a liquid, but it is sticky is very high, very slow and very slow flow of the liquid. You say, really? Otherwise, put it inside the funnel, drop to me!
This drop is really born, and spent 69 years.
Trinity College Dublin, Ireland (Trinity College Dublin) physicists, from October 1944 onwards, put some asphalt on the funnel and let it slow stream of 69 years, to July 11, and finally dropped a drop, This process has the whole photography.

How? You think it is worth it to wait 69 years? According to the process of dripping, the research team calculated that the viscosity of the asphalt group of 2 × 10 7 Pa s, is about 200 times the viscosity of honey.
This experiment is not the first asphalt dripping experiments, University of Queensland have another experiment longer history, since 1927 began, due to the use of different asphalt and has already dropped 8 drops, but unfortunately, in 2000 that drop, drip, when the webcam shot just broken, the result "black screen", we had to wait until this year to see Trinity College Dublin this drop.
However, the University of Queensland experiment may also be dropped in the drop this year, I hope to see them do another failure of the webcam. Asphalt can be like water dripping, but if you knock with a hammer, but it will break into pieces, natural science is not it wonderful?
