Samples are withdrawn from the hot solution and quenched at room temperature to produce a series of increasing particle sizes and observable change in color.


How to make a homemade electroscope

The homemade elctroscope consist of a vertcal copper metal rod, which has a kind of sphere on the top and at the opposite end two sheetd or flakes of aluminum foil.
