As part of the protest against the G20 coming to Melbourne in 2006, I produced a mock package of headache pills (actually musk lollies) and some friends and I dressed in white lab coats with blue lab head coverings and handed these out to people watching the parade/carnival as a way to engage bystanders.
Inside the box was a paper-thin information leaflet similar to those found in medicine boxes with serious information about the issues around the G20 and a packet of about 50 pink musk sweets. Yum!
