Sometimes you just keep on using low technology equipment because it is not worth changing.
A tea pot is one such device. However the age old problem of the spout dribbling all over the place has finally been dealt with. Read the full triumphant story here.
Now not to pop anyone’s balloon but someone had told me why this happened a long time ago. I thought it just wasn’t worth the hassle of engineering a solution that could be retrofitted or replacing the teapots and that new teapots would have this super dooper new spout built in. In the meantime the servants need to be sent back for some NVQs. The PM should get on this straight away.
But now the final solution has finally arrived and finally I can have my cup of tea and cucumber sandwiches without the stress of dripping tea all over the place. The world is saved.
In actual fact the reason any fluid follows the surface on a curve is because of the Coanda Effect. This is ignored because most people do not understand it and / or think it applies except in some very special cases.
Speaking hydrocapillarily, what if we don’t want to repel water?
Ivan,
Fluid dynamics is a science that can’t resolve one of our oldest lasting fluid flow concerns. Why can’t men aim at the bowl?
It’s a puzzle that will elude us for all time. When our species wipes itself out of existence by turning green and when the ants have evolved to examine fossils that will be the question they puzzle over the most.
James,
We freeze it and glue it in place.
