I *nearly* typed a reply to this then realised I'd be giving away a recipe to make boxes muchly harder to detect.
In fact I think this thread is getting towards TMI state. While I appreciate freedom of information and everything else please people be careful, enough numpties with chipped boxes without giving extra info away *cough Escapee cough*
Actually there are other ways to detect chipped boxes that just dissing each drop individually but that's another thing to get into.
