The oil drop experiment was performed by Robert A. Millikan and Harvey Fletcher in 1909 to measure the elementary electric charge (the charge of the electron). The experiment entailed observing tiny electrically charged droplets of oil located between two parallel metal surfaces, forming the plates of a capacitor.
Oil Filter. If your oil filter is long due for a change it will become clogged with oil black, used oil. This will not only prevent it from functioning properly but it will also cause it to leak. It will get over bloated with used oil and that has to go somewhere. To stop that kind of oil leak, simply change your oil and replace the filter with a new one. Oil filters are not very expensive and they are very simple to replace.
