And I can also explain how it is solid. You know how when you sprk some watr it seems to stop in mid-air? That is because sprk itself is a solid, and when you sprk something conductive, it turns it into sprk, but just for a couple of frames. Then, it turns back into whatever was sprked.
I know how you did that. Console! !set type qrtz sprk, then !set life sprk 999999.
