Here’s something fun for you physics geeks: my aunt in Taiwan has this bronze bowl with two handles. You add water, wet your palms, and then rub them on the handles. If you get the bowl resonating just right, then the water ripples and eventually sprays up in a shower of droplets. Googling turns up things like “Tibetan dancing water bowl” and “resonating water bowl” that you can buy online. I shot a little video of myself demonstrating how it works.

On my first attempt, I got the bowl to resonate at a much higher pitch (and much louder), but without the fountain effect but eventually figured it out. Hit the jump for a couple more photos and the video.
