It _is_ just a pain. Any idea that anyone is the least bit more safe because of these utterly moronic and incompetent 'solutions' is that of someone equally moronic and incompetent.
If there's no metal in it, put it in your pocket or on your person. Noone would be the wiser. If you really must get even more liquid or gel on there than can fit in your pockets fashion a container to look like a large, innocuous, non-liquid/gel containing object. Voila!
