Researchers at the University of Texas at Austin created the world’s smallest test tube in 2009, using carbon and a germanium wire with a gold tip, viewed under an electron microscope to observe materials melting when exposed to heat.
The tubes can reach one-thousandth the diameter of a strand of human hair. In 2009, researchers at the University of Texas at Austin set the world record for smallest test tube experiment when they created the microscopic test tube as part of an experiment to see how nanoscale materials react to high temperatures. A test tube was created from the carbon and the researchers inserted a germanium wire with a gold made of gold. Because the test tube was so small, it had to be viewed under an electron microscope to allow researchers to observe how materials melted when exposed to heat, in order to learn more for future materials technology.
