You may think its a joke hovis, but if like me you had succesfully compleated a SIA level 3 security licence course you would know that certain ingredients extensivly used in chinese cuisine can when mixed with certain other items (which i cannot of course divulge here) be used to easily construct a very potent explosive device, so next time your chinese or indian take away is confiscated be aware its not because some petty minded security officer is acting in a fit of pique but thanks to his extensive training he knows the risks that seemingly innocuous items can pose.
