Time fountain slows down, reverses time (http://www.engadget.com/2006/08/09/wow-your-friends-with-your-very-own-time-fountain/)

At least it appears this way. For the engineers among us, this would make a fascinating project.

Awesome! I did have to see that.. But now that I've seen it, what will I do with my life?

That is a brilliant way to create a special effect. Good stuff, Doc !

technically its not slowing anything down, the illumination makes it appear as if it has. If you notice while he's cutting the drops, the spatter randomizes because its actually different drops. Go to a science and discovery museum, they have big versions at almost every one I've ever been too. The coolness factor is that he built it himself. I'm actually pissed that engadget didn't get plans as I would love to have one at home!!!!

If you read it his thing even says that it doesnt actually slow it down, we know that :tongue: were just impressed it looks like it does


The basic principle of the "Time Fountain" involves fluorescent water for extra leet looks, and UV LED strobe lights that are timed in such a way to make the dripping water look like it's slowing down, stopping or even dripping backwards.

Kind of off topic because it was not a special effect, but you are probably also familiar with the use of a Bose- Einstein condensate (http://en.wikipedia.org/wiki/Bose-Einstein_condensate) in 1999 to slow the speed of a light beam to about 17[1] (http://en.wikipedia.org/wiki/Speed_of_light#_note-1) meters per second, and in 2001, they were able to momentarily stop a beam[2] (http://en.wikipedia.org/wiki/Speed_of_light#_note-1)
