The present invention provides an incentive for buying a ring binder or a spiral notebook. The invention is comprised of a vertical mixer containing stationary knives interacting with rotating knives. The holder may be rotated or pivoted so that the angle of incidence of the ambient light can be substantially perpendicular with that of the solar elements carried by the holder to generate an optimal amount of electrical power therefrom in order to power the dispenser. The relay drive unit in receipt of the detection signal generates a signal to turn off the system relays.
