We all know that homeopathy is a waste of time, right? Even my spell checker refuses to acknowledge its veracity. (But, then, it also disputes the word ‘blog’.)

On 30 January, a bunch of ‘skeptical protesters’ will gather at Conway Hall to take a mass overdose of homeopathic remedies. Participants will each down a whole bottle of homeopathic ‘pillules’ in protest at the stance of Boots, the high-street chemist, which continues to vend the pills despite their utter uselessness.

To take part, either at the venue or from home, follow the instructions here.
