ABSTRACT:
An educational doll, useful to teach toilet training to young children, dispenses measured portions of superhydrophobic sand into water, perhaps contained in a transparent commode, scaled to the size of the doll. The superhydrophobic sand collects on the bottom of the commode as a cohesive mass, simulating a bowel movement. The sand can be dyed brown to enhance the visual image imparted to the child. The commode can be equipped with a trap door to simulate flushing of the toilet. When the water is drained away, the sand will be dry because of its superhydrophobic property, thus, easy to handle and reuse.
