There is a myth that, in Dwarf Fortress, magma flows more slowly than water.
This is not the case - they flow at the same speed.
Of course, if the water is coming from an infinite source, that's an entirely different (and unrelated) scenario.

I'd like to see this experiment repeated without the use of a pump to move the magma to it's destination holding room. (IE the magma is flooded into the room normally and then once full, sealed from the source with a floodgate.

Mechanoid: I don't see how that would make any difference, unless you're under the mistaken impression that pumps impart pressure that persists after they are turned off (hint: they don't).

Very nice job, Quietust! An essential piece of mythbusting.
I performed a similar experiment this month, but I got overambitious and set it up to perform several trials, and the resulting video came out too large to post on DFMA. I was going to get around to redoing it but you nailed it.

A bit of historical perspective: back in the old 2D versions, magma did flow significantly more slowly than water, but when the game went 3D this stopped being the case.
