Finger prints leave very fine 'grease' traces. To make these visible it therefore takes a very fine powder which is non-reactive to the chemicals in the prints. Sugar ans salt would be too coarse and also react to the prints themselves perhaps removing them or spoiling them

What is a variable in which can freeze faster salt or sugar?

If you're trying to set up an experiment, the manipulated variables would be salt and sugar, and varying ratios of salt to water or sugar to water. Say you wanted to find out how fast water froze if it had sugar in it, and wanted to compare it to how quickly it froze with salt. Your controls would be the amount of water, the type of container, and the temperature of the freezer. You could pour 18 plastic cups of water, 6 plain water (the control), 6 with salt and 6 with sugar. You could also vary the amount of sugar or salt in the water (say, .5% to 2.5%, with an increase of .5% in each cup).
