ABSTRACT:
A method of storing volatile substances comprises the steps of cooling the substances, and maintaining the saturated vapor pressure of the substances no higher than normal pressure. A container for storing liquid helium blocks superfluid surface flow of liquid helium by providing means on an inner wall or outer wall of the container. A method of controlling a surface flow of superfluid helium includes providing a flow suppressing surface within the container, and causes the surface flow of superfluid helium to impact upon the surface.
