zhwj Posted May 1, 2006 at 07:10 AM Report Share Posted May 1, 2006 at 07:10 AM Had visitors in town yesterday and went on one of those all-in-one Great Wall tours where you get dragged to lots of tourist stops. I take the view that the guide's patter is made up of a few facts along with a generous helping of exaggeration, urban legends, and outright fabrication. So I'd like to check up on one bit: Any idea what the story is behind the story that Nixon was struck dumb with amazement when he saw a demonstration of jade teacups that could be filled over the brim with tea without spilling?

geraldc Posted May 1, 2006 at 08:52 AM Report Share Posted May 1, 2006 at 08:52 AM That just sounds like a practical demonstration of meniscus. The surface tension of a liquid allows it to curve above the rim of the container. Quote Link to comment Share on other sites More sharing options...

Try it out with a plastic coffee cup, works just as well, just pour the water (or whatever) in carefully. Quote Link to comment Share on other sites More sharing options...
trevelyan Posted May 2, 2006 at 02:00 AM Report Share Posted May 2, 2006 at 02:00 AM Did she mention that the Chinese invented water too? Quote Link to comment Share on other sites More sharing options...
zhwj Posted May 2, 2006 at 02:42 AM Author Report Share Posted May 2, 2006 at 02:42 AM The effect in this instance is magnified by the shape of the teacup lip and the transluscence of the jade at that point, so it looks more impressive than your standard overfilled water-glass meniscus. What puzzled me, however, was not the effect itself, but the fact that Nixon reportedly was so amazed that he wanted to take this national treasure home with him, only the jade commune wouldn't let him. Does this story have any basis in fact (ie he gave the demonstration a polite smile and thumbs-up), or is Nixon's name being attached to what is essentially a street-hawker's pitch?
