Scales are not just for cooking but are also scientific tools as this item about precision balances shows.
C/U of a pair of old fashioned brass scales standing in front of faun coloured curtains. A woman's finger is pulling down the weight of the scales. M/S of a man in a white laboratory coat, Douglas Bradley, sitting in front of very modern scales produced by Oertling, manufacturers of precision balances. C/U of Douglas' hand adjusting one of the knobs on the scales. M/S of the top of the modern scales showing that the basic principle is the same as the old fashioned scales, except that these scales can measure accurately to one ten thousandth of a gram. M/S of Douglas adjusting the weights on the modern scales. Panning shot from Douglas' face in deep concentration to the tiny weights hanging from a series of hooks on the scales. C/U of the "precision balance" being tested. Tilt up to the weights on the hooks. M/S of Douglas getting up and moving to a cup and spoon on the sideboard. C/U of the Douglas' hands carefully spooning out ash from the cup onto a small red dish. Douglas uses a pair of tweezers to pick up a particle of ash. C/U of the particle of ash lying on the shiny metal plate of the "precision balance". The narrator explains how useful these precision balances are in the detection of crime - by weighing the ash scientists can determine the brand of cigarettes the suspect was smoking.
M/S of a woman in a white laboratory coat, Pamela Uwin, sitting in front of another set of high-tech scales. She has a piece of paper in front of her. She picks up a fountain pen. C/U of Pamela's hands drawing a cross onto the piece of paper - the narrator comments "measurement can go too far; you can even weigh a paper kiss in the balance and if you find it wanting you can always write back for a bigger one!" C/U of the piece of paper held by tweezers being placed onto the scales, a glass shutter slides down from the front of the scales to prevent dust interfering with the measurement.
