In the past few months, we have covered a couple of cool Kamenstein World of Motion Kettles. This Carousel Kettle is also worth a look. It is a steam motion kettle that comes to life as your water boils. Simply pour some water in, put it on your stove on medium/high temperature and wait till your water boils.
When enough steam is generated, the little horses will start spinning on their own. The above video shows this motion kettle in action.
