How can I make a storm glass at home?

To make a storm glass at home, you will need a clear glass container, distilled water, rubbing alcohol, camphor, and potassium nitrate. Mix the distilled water and rubbing alcohol in a 2:1 ratio, then add a small amount of crushed camphor and potassium nitrate to the mixture. Stir well until everything is dissolved. Pour the solution into the glass container and seal it. Allow the storm glass to sit undisturbed for a few days to observe the crystal formations that indicate changes in atmospheric pressure.
