Everyone knows about the invention of Velcro being based on observation of the burrs on Burdock seeds by Georges de Mestral.
Today’s invention is to take a step back from that and apply such burrs in a viral marketing campaign.
Natural burrs would be attached to a number of fabric patches applied in critical locations within eg an airport.
People passing would brush by these and attract some onto their clothing. In the train or elsewhere, later, these would transfer from person to person.
Each burr would have a small label attched, bearing a web address for the product or service being advertised.
The burrs themselves would be biodegradable and cause no damage to anyone’s outfit.
