We wanted to promote an otherwise humdrum product in a way that would catch the attention of people and engage them. We set up installations outside pharmacies, consisting of a magic slate which could be written/drawn on, and then erased with a single stroke. The magic slate was placed on a life-sized cutout of the human digestive tract and operated by a representative of Baidyanath Gas Guard.Customers were asked to draw their favourite street food items on the magic slate, whereby the brand representative made the doodle disappear by moving the slider to the right.

The promotion was hugely successful and resulted in more than a 23% increase in sales of Baidyanath Gas Guard.
