As helium is cooled to lower and lower temperatures, greater and greater fractions of it demonstrate quantum effects.
At lower and lower temperatures, greater and greater fractions of liquid helium become superfluid ( http://istd.gsfc.nasa.gov/cryo/introduction/liquid_helium.html). Superfluid helium can do some seemingly impossible things, like climb up the walls of containers or leak through pores ( https://www.youtube.com/watch?v=TBi908sct_U&feature=related ) that are too small for normal liquid helium to pass through. At this point, superfluid helium is demonstrating the effects of quantum physics, which makes it especially tantalizing to physicists. Now, in a new study, an international team of physicists has taken images of tiny droplets of superfluid helium, finding that even very small amounts of superfluid helium act unusually.
