TUB SUB
Floats as a boat, sinks as a sub! This interactive, transforming tub toy encourages cause-and-effect thinking, reasoning, and teaches basic physics. When the soft teal periscoped top is pushed into the stiff orange base, the toy floats - when fully extended and submerged in water, it sinks!
