Seeing a macroscopic quantum state with your own eyes!

Tomorrow's lecture is on the phase diagram of helium and superfluidity. I will show them some cool videos of superfluid 4He. In previous years I showed the video that Jack Allen made at St. Andrews in the 1960's.
However, there are now ones on Youtube. Hopefully, this will stimulate some students to look at some of the videos at home.
One quantitative goal of the lecture is to use dG=-SdT+VdP to estimate the magnitude of the fountain effect.
