The silent water jet
A truly unique phenomenon,
Water is falling in a bright vertical jet from an altitude of about 160 cm into a pool, completely silent.
This jet can be disturbed by touching it, reveling the stored energy in form of a sharp sizzling noise, but it is restoring itself in a short amount of time. This unique form of water is only possible due to specially created mechanism which makes use of surface tension in a particular way.
No additional pressure or any kind of nozzle is necessary.
