Located in Seaham Hall (UK), the Vortex Fountain “was created using a large acrylic polymer cylinder which allows an air-core vortex to form as water is pumped in a circular motion.” Video after the break. Click here for first picture in gallery.
Not surprisingly the fountain also relies on a heavy-duty water filtration system which is necessary to keep the vortex clean and spinning properly.
