Magical, Mystical Storm Glass: Space & Weather
Today our meteorologists-in-training discovered the properties of the chemicals (potassium nitrate, ammonium chloride, camphor, and ethanol) in a storm glass. They then made their own storm glass and learned how they “predicted” weather. The premise of the functioning of the storm glass is that temperature and pressure affect solubility, sometimes resulting in a clear liquid and other times causing precipitants to form. In similar barometers, the liquid level moves up or down a tube in response to atmospheric pressure.
Ask your camper: is a storm glass completely accurate? (No, it is not a truly scientific method)
