I mention in my description of this blog "Blogging All Illusions: optical, magical, visual, science, jokes, funny pictures etc..." Here is an illusion made possible because of science. I thought gravity was a constant and that water couldn't flow uphill. I guess I was wrong.
A set of four glass ramps positioned in a square clearly show water traveling up each of them before it pours off the top, only to start again at the bottom of the next ramp.
It is a sight which defies logic, and has become probably the most memorable image of this year's show. (...)
It is a trick which has greatly intrigued the crowds at the Chelsea Flower Show, where Dyson's work is part of the Daily Telegraph's Silver Gilt award-winning garden. People have been queuing up 10-deep to see the fountain, says Mr Phillips, many of them discussing their various ideas as to how it works.
"I stand a discreet distance away and listen to some of their theories - there are some fantastic ideas there, some of them I actually wish I could make.
Check out this site for a flash presentation of the garden and fountain in action.
Is this a trick as the article says? No, this is not a trick, "trick" sounds like something you would find a magician doing at a 8 year olds birthday party. This mix of art and science is a very convincing illusion. People don't line up 10 deep for something that looks like a trick. The BBC article has an excellent explanation (with pictures) of how James Dyson (of Dyson Vacuum Fame) makes water go up hill. If you must have the mystery revealed click here, but be warned for each person who looks a little bit of the magic left in this world dies.
