So I guess some analysis methods:

1. The center of gravity will likely be all off.

2. X-ray or just a powerful enough light

3. My favourite and I wish hamas did this for their pagers: carolimetric analysis (ie: set it on fire and see how many btu’s come out): https://en.m.wikipedia.org/wiki/Calorimeter

(Oops, hezbollah, not hamas!)
