One thought on “Frost, Meet Leiden. Leiden, Frost.

  1. I played with liquid nitrogen when I was an undergrad. I stuck my hand in it. Also, if you pour some on a tray, blobs are held together by surface tension. The interface with the tray is extremely low friction (as the Nitrogen is floating on a layer of gas that is boiling off). The little blobs skitter around in an extremely pleasing fashion. I also recal that, at the time, liquid nitrogen costed about the same as beer. So it was not bad value entertainment.
