Storm Bottle

Place this little bottle on your window sill and it will forecast the weather!

Developed in the 18th century, the storm bottle is a sealed glass bottle containing a delicate balance of ammonium chloride, potassium nitrate, camphor, water and alcohol. These substances form a clear solution in which different crystals form and dissolve based on environmental changes.

A great gift for the budding scientist or weather enthusiast.
