The University of Queensland pitch drop experiment, demonstrating the viscosity of bitumen. The pitch drop experiment is a long-term experiment that measures the flow of a piece of pitch over many years.

At room temperature, tar pitch flows at a very low rate, taking several years to form a single drop.
This method of recovery has remained the main source of helium since. Helium is colorless, odorless, non-toxic, non-corrosive and non-combustible. Helium has the lowest boiling point of any substance , 4.2 Kelvin or â269 Â°C and as a result, liquid helium is the coldest matter on Earth.
