It was a basic snare trap (you know....bend the tree over put a snare on the end and when they step on it the tree springs up and the animal is hanging in the air) but instead of the snare being tied directly to the tree it was tied to several larger balloons filled with helium!!!!! Apparently he bated this thing near his car before bed and by the morning "the balloons" were gone!!!!!
Seems a bit wasteful of helium, how about a slight modification: instead of making them float off into the sky, make the snare trigger a catapult and throw them into another street
