I had this same idea, well, not a dress though. You can get various 
colored water soluble blacklight dyes from glowbottles.com for pretty 
cheap (~10 shipped for 4 colors)

anyway, one large problem is that you need to have a black light shining 
on you. instead you could use glow in the dark powder* suspended in a 
liquid and illuminate the fluid with UV LED's at intervals. this is like 
glow in the dark paintballs, which have a UV flashlamp at the end of the 
barrel to "charge" the paintball as it leaves the gun. except instead of a 
paintball you have a stream of liquid.

yep. looks like he's mixing the fluids in the earlier videos though. 
paraffin (lamp oil) works pretty well too, if you don't mind being covered 
in tubes full of flammable fluid.

please elaborate?
