The child removes the plastic measuring cup from the end of the cardboard tube. With her right hand, she pushes pellets horizontally to the end of the tube. With her left hand, she propels the pellets off the end of the tube to land in the tub at the end of the table. At least most of the pellets land in the tub. She repeats her operation, but this time it looks like her hands are in sync; as she pushes with here right hand she propels with her left all in one motion.
