Amazing effect of HV on H2O.

Cool Video

I smell a weekend experiment!

also: woot five stars!

Tried that with distilled water and a rectified flyback. I succeeded in making just miniature bridges (about a mm or so), when I increased power the bridge started boiling, arcing and melted my plastic cups mistrust . I guess the water was not pure enough...

maybe the plastic cups weren't ideal....

I have glass beakers and several HV PS at school, I'll be getting my physics instructor to help me

I think TDU has this on his site some where. Using a van de graff I have managed to get tap water to jump a few MM up from a small pool, perhaps you could do that with a CW multiplier or a beefy DC flyback.

It seems that voltage rather than current seems to be important, so maybe someone could try this with a rectified doubled NST?

Also might be worth using triple distilled water to see if this has any effect (less ions = lower current maybe?)

I think what's important is to have the purest water possible. I had enough KVs but the water was probably just too "contaminated".

It took me a while to find it on my own web site. The article is here.

There's lots of interesting stuff to do with deionised water.

I just tried this, very cool but such a mess with all the water running over the edge at startup, never got the thing to work with a piece of thread or hair.

But you can see the pictures and a small video of it here: Link2
