Development of thermal teapot

According to a British black tea exporter, boiling water of ideal temperature is poured over tealeaves, more than half of the leaves will float while the rest drop to the bottom. Such a movement of tea leaves is well known as “jumping” phenomena. However, depending on the condition of the boiling water, it does not always occur “jumping”. In order to analyze the “jumping” phenomena, we investigate automatic “jumping” phenomena through the teapot image sequence.
