We just love this clever little Tub Sub!
Why do things sink or float?, Tub Sub knows, as a boat it floats as a Sub it sinks. For a floating boat, push the flexible blue part down. For a sinking Sub pull the blue part up and fill the bottom with water. Only the periscope will stay above the water.
Great for fun water play in the bath or outside in a paddling pool.
