Emerging Tech project proposal

Create illusion of ripple/wave effect on silk. Original idea was to put a series of pressure sensors on a piece of art. I couldn't figure out how to tell the user where to push in a visually appealing manner so I changed a few things up. The fans will now be activated by one of four IR sensors. The infrared led will be attached to a bottle made from foam and paper mache. Once the led touches one of the IR sensors it will trigger to fans to operate for however the long. The project should be fairly cheap and require no class materials, but I do need to order the parts.
