Helium usually reminds people of colorful gas balloons. However, helium is much more than the filling for these children’s treats. It also helps quantum physicists to study the most exotic and hidden properties of matter. Scientists have now discovered a condition by which electrons trapped on the surface of liquid helium become incompressible at very low temperatures and under microwave radiation.
