I like your idea about the yellow electricity a lot. If possible, a shot of the thingie on the wall before it's ripped off might make it even more clear. In that shot (maybe just a second or two before it's torn off), have the thingie pulsating and glowing with yellow electricity. This might be asking too much, but if the thing can even be arcing with yellow electricity BEFORE it's torn off, that would be even better.
