Ok, I need your guys help on this one. Last night, someone vandalized our greenhouse, and none of us in my family can figure out how the heck it was done. Ok, I'll start from the beginning:

In our backyard, we have a shed, and a green house, the shed is at the very back of the yard, followed by the greenhouse. The green house isn't used for growing plants (anymore), we just use it for storage. Inside we have bikes, deck chairs, pool stuff, and all my bales of pine for my rats.

This morning we discovered a large puncture in the greenhouse, AND a puncture in one of my bales of pine. The piece of insulation punched out of the wall is missing, and there is NOTHING inside the greenhouse that could be the culprit. And for the love of god we cannot figure out what kind of device, stick, board, or projectile could have done this, here's the pics:

Outside closeup of puncture, there is some sort of circular indent in the plastic, almost like it was a paintball (but there's no paint!)


Punched out insulation, missing


Inside view of the puncture


View of the inside of the greenhouse, the puncture in the bail, is actually HIGHER than the hole in the greenhouse wall

So guys, any idea's as to what the heck could have done this?!
