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!)
