American Scientific Resonance Chinese Spouting Bowl | Create a Dancing Water Fountain Display | Relaxing and Satisfying Experience TRANQUIL AND PEACEFUL - Water drops shoot up, quickly becoming continuous streams, like tiny fountain jets. The visual and audible display is relaxing to feel and satisfying to experience whether youre the one performing with the bowl or watching somebody who is. FEEL THE MOTION OF THE OCEAN - The Resonance bowl is perfect to demonstrate the behavior of waves and their interactions. Due to the vibrations caused by the rubbing of the handles, the water surface begins to ripple around the rim and the faster you rub the more excited the waves become. BEAUTIFUL DISPLAY - Four Han dragons can be seen in the bottom of the basin, spraying streams of water up the sides of the bowl. The rubbing of the palms against the metal also creates a peculiar sound unique to this product. Don't be surprised when anyone within hearing distance becomes immediately intrigued by the strange intonation it produces! MAXIMIZE THE VISUAL EFFECT - For maximum effects, we recommend the use of a resonance mat (not included). Because of the material and design, this mat helps prevent slipping and allows for larger standing waves by preventing vibrations from transferring to the table. A damp, folded bath towel may also work. HISTORY OF THE FOUNTAIN -The Chinese Spouting Bowl first appeared in the Han Dynasty (202 BC - AD 9). It is said that the bowl was a kind of plaything for nobles, gifted scholars and socialites in the Ming Dynasty. It was believed to foster happiness, prolong life and increase strength.
