The Teapot Effect: Why Teapots Drip

Jan 2, 2013

Joseph B. Keller is an immensely distinguished scientist. Professor Emeritus in engineering and mathematics at Stanford University, he may be known best for the Geometrical Theory of Diffraction and the Einstein–Brillouin–Keller method.

But his major work – honored with awards that include the National Medal of Science and the Wolf Prize – might not fully convey Dr. Keller’s sense of playful enthusiasm and perpetual curiosity.

What sparks the curiosity of a man who has attended lectures with Einstein and partied at Heisenberg’s house? For one, Joseph Keller is into teapots. Really into teapots. In fact, he is the world’s recognized expert on why teapots drip.

Like many of us, Dr. Keller had long observed the pesky problem of that little bit of tea that always seems to run down the outside of the spout and drip into our laps. “Then, in 1956, I heard a lecture,” he told me. “An Israeli scientist reported he asked 100 physicists why teapots drip and they all said it was due to surface tension. This scientist did some experiments that proved it couldn’t be caused by surface tension, so what is the explanation? I wrote a paper, ‘The Teapot Effect,’ shortly thereafter, showing that the effect occurred through fluid and mechanical forces.”

Dr. Keller showed that it was air pressure, not surface tension – that causes drips. “It is simply that at the pouring lip the pressure in the liquid is lower than the pressure in the surrounding air,” he said, “so air pressure pushes the tea against the lip and against the outside of the spout.”

In 1999, he and his colleague Jean-Marc Vanden-Broeck described the final act in the drippy teapot scenario when they calculated where gravity makes the drop fall off the pot. For this, Keller won his first Ig Nobel Prize Award from Harvard, which celebrates the unusual and imaginative in science. (His second Ig Nobel Prize was awarded in 2012 for calculating why a jogger’s pony tail swings side-to-side while her head is moving up and down.)

Can Dr. Keller look at a collection of teapots and make a reasonable guess at which are more or less drippy? “Yes, I believe I can,” he said.

He told me there are three things that help make a spout drip-proof. “The first thing is this,” he said. “If the teapot spout points up and then straight down at the pouring end, then the tea will flow back into the pot when the pot is turned upright again and a drip would be almost impossible.”

“Number two is this,” he said. “If the lower lip of the spout is sharp, as is the case with metallic teapots, then the trouble is ameliorated. The sharp edge would help prevent the tea from turning the corner. It’s still possible to drip but less likely if the tea is coming with any force. There are little metallic tools with sharp edges that fit over the end of a teapot spout that can covert a bad spout to a good one.”

His third piece of advice for avoiding drips is not to have the teapot too full. “Tea from a less full pot will flow with greater velocity. The faster the flow, the less likely it is that the tea will cling to the lip.”

Next Prev

Fundamental forces in our universe make teapots drip, the same forces that make life itself possible. So if we found ourselves in a universe where no teapots ever dripped, is it possible we might not be able to survive there to enjoy the tea?

Dr. Keller chuckled at that idea. “The best I can tell you,” he said with full scientific rigor, “is maybe.”

    Teapots always remind me of Beauty & the Beast's Mrs. Potts, one of the kindest of all Disney characters. I always thought tea pots dripped because I had a bad teapot! Now I don't feel so unlucky knowing EVERYone has this problem. ; )

    "...So if we found ourselves in a universe where no teapots ever dripped, is it possible we might not be able to survive there to enjoy the tea?" Interesting question...as a tea lover, my question would be, would it be worth surviving in a world without tea? Amazing constellation of teapots :)

    They are the smallest and the most seemingly simple inquiries which astonish us at the complexity which they may be founded. Why does a tea pot drip, why does a pony tail swing side to side on a jogger, it's the simplest things which sometimes arouse the greatest awes.

    Physicists are always getting caught up in the beauty of explaining everyday mysteries as much as those more obviously central to the field. Thanks for an enjoyable post! I enjoyed it as a physicist, artist and tea drinker.

  • AdrienArt

    Adrien Miller from AdrienArt said 4 years ago

    I usually focus on having a sharp edge on the bottom edge of the spout to prevent the drips. From my experience making teapots it's seems to have been the main key in cutting the stream of fluid so it doesn't roll around the tip of the spout. This article gives some nice extra insight. I think pouring technique can also be helpful to avoid drips. When the cup is nearly full, quickly tilting the pot back while pushing it in the air forwards towards the spout seems to aid in tea getting pulled back into the pot. Thanks for featuring one of my dreamer teapots!

    I was pretty fearful to make my first teapot, 25 years ago, since my teacher had said it's the "epitome" of being an excellent potter. But, once I tried, I found I have quite a knack at it. I even make then pretty teeny, about 1/2 inches long by about an inch tall. And, yes, turned in three pieces, with my fingers, just like the larger ones. Body, Spout and Lid, then put them all together! It's fun! ♥♥♥

  • dorothydomingo

    Dorothy Domingo from dorothydomingo said 4 years ago

    I must admit when I've made teapots my main emphasis has been on the design - making the spout, feet, lid, body and handle work together in an artistic way. A functional spout without drips was just a little too intimidating! I don't feel so bad now that I learned a lot of teapots drip. I may give a functional rather than sculptural teapot another go!

    Shirley from EyeCandyandMore said 4 years ago

    Ha !! How much fun this blog was to read !! I drink and serve tea several times a week. I own about 47 teapots. If I find one I really want, I ask if I can try it first because the flow of the tea from the spout to the cup is very important to me. The tea must come out in a perfect stream or I won't buy it. I served tea tonight actually, and filled my pot three quarters full to make four cups. I did notice that after pouring the first cuppa one drop dripped.. It didn't happen again after that first cup. I usually try to give the pot a quick lift to avoid the drip and sometimes it does work actually.. lol.. I totally enjoyed this read.. it was lot's of fun.. ty

    Amazing! I love the fact that the world expert on teapot drips was inspired by an Israeli scientist too! (yes, a little patriotic pride is dripping out of my spout here too) It's amazing how such a little thing like a teapot's drip can be so closely intertwined with the grand forces of the universe that hold everything together. I say that's a perfect call for a cuppa!

  • kiracall

    Kira Call from KirasPotshop said 4 years ago

    Also, teapot spouts are really tricky, even if you've been taught the "right way" to make them. The trick is making sure the spout has a larger base in comparison to the opening of the spout, and the end of the spout should form a straight channel-- for example, geometrically conical spouts aren't the answer because the water isn't channeled and when it leaves the spout the stream will probably gush out because the fluid is being channeled to a smaller point than is necessary. Trumpet spouts are also problematic. If the spout dramatically flares out at the end, or gets wider than the narrowest point, the fluid will gush out unattractively, no matter how sharp the lip of the spout may be. The opening of the spout should be the narrowest point, but there should be a "straightening out" section to redirect the water in a fluid stream, and then the lip of the spout should be crisp. Hope this tip helps teapot adventurers :)

    Yes, Sharon, it was pretty "nerd-awesome" to talk to Dr. Keller. He was very generous with his time, and stopped frequently to ask, "Do you understand?" as he explained the Teapot Effect. His patience and clarity reminded me of what makes a teacher exceptional. And I cannot possibly tell you how much fun it was to shop for teapots on Etsy. So design-rich, experimental, and adventurous! So much variation, all in service of the perfect pour.

  • blainedesign

    Karen Brown from blainedesign said 4 years ago

    It's so interesting to hear the different design strategies that echo the Teapot Effect. For example, AntWear, the hole in the lid is probably connected to the idea of using air pressure to force the tea out, similar to filling the pot only part way. And Kira, the narrowing of the spout that you so beautifully describe probably increases the velocity of the tea and therefore decreases the likelihood of a drip. It's so interesting to hear how observant craftspeople have solved everyday problems through responsive design.

My biggest concern on teapots and pitchers too, is the sharpness of the angle on the outside, to encourage a quick "cut off". Rounded edges in my experience, drip every time. Same is true of a pitcher spout. I also concentrate on the flow of the liquid from the pot, so it has a quick flow up a channel to a quality pouring spout! :-) I'm big on quality handles, and quality spouts! No detail is too small!

    After reading why teapots drip, I no longer think I need a new thermos because that one will drip too. How did I miss this article? Even though I know next to nothing about it, surface tension just seemed too obvious. But count on those Israelis to figure it out - What a sharp bunch!
