Just in case you missed Al Roker's weather forecast and your smart phone isn't speaking to you, you need a way to tell what the weather will be. This elegant Weather Predicting Swan Glass does it old school.
Basically the swan is a simple barometer. Sailors used barometers to predict weather for more than 400 years and weather forecasters today still measure barometric pressure in their work. When the weather is fair the black liquid in the swab will be low. When a storm approaches and the pressure drops the liquid will begin to rise. This is a lovely gift for all sorts of bird lovers.
