Abstract: A method for measuring with a flexible dipstick the nonvisible level of liquid nitrogen in a container. The dipstick, made of a solid plastic strip having a flat cross-section and a dark color on which is printed a visible scale, is inserted into the liquid nitrogen-containing container for a short time. The dipstick is then rapidly waved in the air to permit frost to form on the cold portion that was immersed in the liquid nitrogen. The dipstick has a relatively high width-to-thickness ratio to provide waveability and flexibility for quickly forming the frost line and for permitting compact storage when not in use.
