Physicists at St. 31 College in Dublin in 1944 tried to measure asphalt tar viscosity at room temperature, hoping to witness the moment when the pitch fell from the funnel. Not long ago, the camera recorded this magical moment for us ...
"The viscosity of tar is 230 billion times times that of water, or 230,000 times times that of Honey," the school's physics department wrote in its experimental report. ”
This is one of the oldest experiments in the world. As early as 1927, the University of Queensland in Australia had similar time. By now, it has collected 8 drops of tar that fall at room temperature. In this way, physicists can not only measure the viscosity of asphalt, but also show people the fact that solid materials can flow.
