This creation is originally inspired by Nate's True "Time Fountain" (thank you Nate!)
The "Magic Fountain" is based on the principle of the Stroboscope. http://en.wikipedia.org/wiki/Stroboscope
With strobe light we get the illusion of freezing the drops of water in midair, slowed or reversed!
I made this fountain using a little submersible water pump inside a decorated jar, fluorescent water (with highlighter's ink) and UV LEDs, to obtain strobe light, using a simple strobe circuit based on a pair of ne555 (with a low duty cycle).
With this circuit we obtain a strobe light with duty cycle and frequency both adjustable via two potentiometers.
The transistor (2N1711) can handle a maximum current of 500 mA.
I used 18 LEDs UV.

Behind the fountain we can see the pipe to dripper(this dripper: http://servizimedia.altervista.org/fontana/img/Contagocce.jpg from infusion medical kit) and a little black tap, to reduce the waterflow.
