I'd like to know how to alert nearby NPCs that the player is doing something fishy when he casts a spell. I can probably do it via scripting but I'm guessing there's a better way to handle it via the CK.

Specifically, it's a telekinesis spell that works on containers: cast it and it pulls a distant chest to your location. For some odd reason I think this might tend to alarm people such as guards, who would be at the very least curious, if not hostile, and would want to follow the chest in the direction it went.

The spell isn't blatantly hostile- it shouldn't turn townsfolk hostile, but would alert enemies (and might piss off the owner of the chest if they were only neutral to the player).

The effect I want is similar to a "Noisemaker" arrow from the Sneak Tools mod I THINK this is done by setting an Explosion on the spells projectile, but I don't know where to go from there.... radius? image space? loudness? ... what would make a guardian suspicious that his chest is sliding way from him?

Also, how could I "jiggle" Havok items that might be placed on the container that is moving so they fall down?
