Since the discovery of the purple acid that does not corrode i started paying more attention to particles and made another discovery EDIT: it seems it was discovered already some time ago, howver i never saw mention to it.
I found a way to make fire particles that have some odd properties:
-they do not burn themselves like regular fire and do not decay -they are pretty stable -they turn into normal fire when touching any other particle (so far) except SHIELD, PIPE and PORTAL (not fully tested yet) - works better with solids. -they act like a gas -they are affected by reverse gravity (they go up at a regular rate without any pressure) -they turn to smoke when cooled -They turn into plasme when in contact with GOL particles
And i made a contraption, however crude, that can make a fairly large number of those particles in an automated process, however it is a bit slow:
LoadSaveBlock(103376);
Feel free to modify it so it works better.
In fact, i INVITE all the pwoder toy masters and enginner to try to optimize this process, as done with the strange acid particles.
