I have a ton of other fish in the tank so it's pretty easy to put enough food in that it'll get distributed all over the tank quickly. If I want to only feed frozen brine shrimp or something, though, I'll use a few chunks, with one that I'll hand feed the Uaru with to distract her. I can move it around a bit and she'll follow it, which gives the other stuff time to sink to the bottom or get spread around.
They were in the Indianna Jones movies anyway...
