Guerilla marketing

i liked the Quarter one the best because no only does it make people stop and look but it also show the customers that might buy the product at a later date know what it is all about like in the quarter video it showed the customer just how strong the glue is by making them try to get the quarter off the ground and they added a small ad that lets the people know what is happening and what product was used to make it happen but it is also small so it does no give away the joke like for example if they put a huge poster that said try to pick up this Quarter most people would assume its a joke and not even bother to look
