I think I'll have to test the ammo can vs a Faraway cage. I think seeing if a cell phone will receive calls and texts might be a decent test.

Use a microwave and copper mesh as well. If a call or text gets through its definitely a fail.

I need to pick up some 50 cal cans and a 30mm can anyway. I may try a 2 way radio as well.

The next science channel coming up.
