In January 2010, nearly 400 activists joined the 10:23 Campaign, in taking to the streets across the UK to participate in a mass 'overdose' of homeopathic products to protest their sale in pharmacies and NHS funding. Michael Marshall of the Merseyside Skeptics Society, who founded the campaign, talks about the birth of the protest, the unique approach to getting everyday people involved, the success of the campaign, and how an idea born in a small pub in Liverpool went on to make headlines across the world.
