Situated at the front of the spin room is an elevated platform. The instructors bike sits atop this platform facing the tight cluster of bikes in front. On the front of the platform is a large glowing advertisment for Sensodyne toothpaste asking "Are you at risk of acid wear?" The reason it glows is because it is white and responds to the UV lights installed in the darkened room. The most disconcerting aspect of this advertising is that the UV light environment also causes peoples teeth to illuminate. Sensory advertising. This promotes self consciousness, planting the seed that perhaps your teeth could be indeed at risk of acid wear> and that perhaps sensodyne might be a good answer to whiter teeth. scary
