Please comment on how we could improve the film (note that the You Tube version blurred the text on the initial info panels).

This technique is the basis of the technique used for detection of biological ice nucleators in environmental samples (Christner et al 2008 Science 319:1214 and Proc. Nat. Acad. Sci. 105: 18854–18859 ). How to determine the number of bacterial cells needed to produce ...
