  • intresting stuff, i hear the viscousity of liquid helium at close to freezing is near zero, anyone know where i can witness this

  • Helium cannot be frozen (though it has been solidified under pressure). Viscosity experiments can be viewed in the other segments of this film.

  • this is some shit that I dont really understand ! im eager 2 tho

  • this is so cool. i have been watching this and the "absolute zero" nova episode on youtube. THANK YOU DR LIETNER, i wish my chem profs were as clear and inspiring as you. oh yeah and GO STATE!!!

  • as chemistry is vice versa!

  • Dr Leitner, I hope you read this as I want you to know that I was fascinated by your experiments. Your lecture is no less wonderful and inspiring today than it was 47 years ago. I wish scientists today could explain what they are doing with such clarity.

    PS A Happy New Year from Glasgow in Scotland

  • No mercury wi freez solid if I remember correct

  • Only at high pressure...

  • id like some solid helium, can it be done

  • That is phase I and II in liquid form?

  • Does liquid mercury have a similar transition property?

  • agreed.
