4A40.15elasticity of low temperatureDisc 08-09Liquid nitrogen and a solder spring, rubber hose, etc.
4A40.20mercury hammerPIRA 1000
4A40.20mercury hammerHk-8Mercury is frozen in the shape of a hammer head and used to pound a nail.
4A40.20mercury hammerH-101Cast a mercury hammer and freeze with liquid nitrogen.
4A40.30smashing rose and tubePIRA 200Cool a rose, urffer tube, or handball in a clear dewar of liquid nitrogen and smash it.
4A40.30smashing rose and tube4A40.30Cool a rose in a clear dewar of liquid nitrogen and smash it.
4A40.30rubber at low temperatureHk-7A rubber hose is dipped in liquid nitrogen and smashed.
4A40.32low temp behaviorTPT 28(8),544A discussion of a heat of vaporization of liquid nitrogen lab and a listing of the usual demonstrations.
4A40.32low temp behaviorH-99Smash a wiener, sheet metal, flower, hollow rubber ball, saw a sponge, alcohol is viscous, a pencil won't mark.
4A40.33cyrogenics day in a high schoolTPT 28(5),321Description of the annual cryogenics day at F. D. Roosevelt High School listing many demonstrations.
4A40.35cool rubber bandPIRA 1000
4A40.40viscous alcoholPIRA 1000
4A40.40viscous alcoholHk-10Ethyl alcohol becomes very viscous at liquid nitrogen temperatures.
4A40.40viscosity of alcohol at low tempDisc 14-05Cool alcohol with liquid nitrogen and pour through a cloth screen.
4A40.50liquid air fountainH-114A fountain is made using evaporating liquid air as a pressure source.
4A40.60absorption of gasesH-116A test tube filled with charcoal is attached to a bent 80 cm tube dipped in a beaker of mercury. When the charcoal is cooled, the mercury rises.
4A40.60absorption of gasesH-117A discharge tube filled with charcoal passes through all the stages to vacuum when cooled in liquid air.
4A40.70burning in liquid oxygenH-121Steel wool is burned after being immersed in liquid oxygen.
4A40.71burning in liquid oxygenH-118Old cigars (and other things) burn well when saturated with liquid oxygen.
4A40.72burning in liquid oxygenH-120While smoking a cigarette the lecturer puts liquid oxygen in the mouth and blows out.
4A40.75reactions in liquid oxygenH-119Drop a piece of potassium cooled in liquid oxygen into water.
4A40.80filtering liquid airH-107Crystals of ice and carbon dioxide are retained in a filter.
4A40.85density of liquid airH-108Pour liquid air into water. As the nitrogen evaporates, the liquid air sinks and oscillates with convection currents.
4A40.90low temperature lattice modelsAJP 55(6),565Arrays of magnetic quadrapoles in square and triangular lattices simulate orientational ordering of diatomec molecule at low temperatures.
