I got this idea from a T.V. show. Particles that stop electricity. This would be some sort of powder that absorbs spark. It would stick to any conductor (cling to sides and bottom) and absorb the spark where it touches. INST would simply not function. Also, it does not damage the conductor in any way, unlike EMP. I don't know if they should be indestructable or not.

STATS:

name: ASPK

color: sky blue

spawn temp: 22C

description: sticky powder. removes electricity

special: can be programmed with a target conductor by ctype, does not automatically obtain any ctype

EDIT: range set by tmp (pixals away from center)

USES:

-stray spark control, to prevent spark from destroying conductive saves (like my Titanic)

-control spark in electronics (with ctype)

-funnier than EMP

UNKNOWNS:

Should it work on things like water and mercury?

EDIT: Density?

OTHER: 

-would not work on obscure things like walls and conducting quartz

graymatter...no, no, no...not block spark between conductors. Stop spark through a single conductor.

Like this:

That only works on plain metal, is solid, and sucks (literally). Not the best idea. (especially if you're already using portals) But I'll use it to make the demo realistic.
