Using the Pro Spin N Sort Bath Spout is super easy and fun! First, attach the battery - operated spout and the spinning gear to the side of the tub with the suction cups. Make sure the spout's blue pump is in the bath water. Then, let your child press the large, silly - eyed button to start the water flow. Your kid can match shapes and sort colors by fitting the gears correctly. Position the spinning gear under the spout to see the physics in action as the water makes the wheels turn and the googly eyes twirl. Place the three bath tumblers under the water stream to experience different effects. Try to stop the spinning propeller with your finger or play peek - a - boo with the float in the tumbler. Stack the tumblers in the swivel arm and watch the water run through. You can also block the water stream with your finger and get a surprise splash. Let your child have fun filling and spilling water. After the bath, store the tumblers on the swivel arm to dry. As for maintenance, keep the spout and gears clean by rinsing them with clean water after each use. Make sure to remove the batteries when not in use for a long time to avoid damage.
