See if you can get the water to spout!
Chinese ‘Dragon Wash’ 龙洗 Lóng xǐ Spouting Bowl
1. Part-fill the bowl (about ½ full).2. Wet your hands well.3. Rub back and forth along the
handles with your hands as shown by the arrows in the picture. Try to ‘go with the flow’ – it works with very little downward pressure.
4. Listen to the sounds produced as you rub. A squeak? That’s good. A hum? Even better! Watch the water as the hum continues. See it vibrate? Keep rubbing and you’ll see water spouts pop up from the surface on or near the fountain marks on the inner wall of the bowl.
5. Still no sound? Your hands may have oil on them.

Public Engagement with Research aimsOur aims are:• Recognising and responding to public
views; • Inspiring young people; • Supporting researchers.
External drivers: e.g. the RCUK Excellence with Impact agenda
Also: HE Access Agreements; subject-based initiatives, e.g. RAEng
