Plasma disolves very fast so would it be possible to say have some way of stabilsing it,
One way would be when it was under pressure (say 5.00)
WHEN PLASMA IS STABLE:
Doesn't burn things, lasts forever (while it is pressurized)
WHEN BECOMING UNSTABLE (pressure drops below 5.00)
Makes a mini explosion (say two dots of fire to each dot of plasma)
WHEN UNSTABLE
Well how it is now, doesn't last long burns,etc,etc

Nice (can't see how thats relevant) but still cool idea...
