Goethe Barometer - Astromedia

If the pressure rises, the liquid is forced back into the sphere against the internal air pressure and the level of the liquid inside the spout drops: fair weather is to be expected. When the atmospheric pressure drops, the level in the spout rises and predicts rain or storm.  

Including syringe and tube for easy filling of the barometer and blue food dye.

A beautiful instrument and a great present!

(The barometer is made from thin glass and children should only handle it under adult supervision!)
