A nautical wonder! Just like the subs found in cereal boxes in the 1950s, this classic toy is powered by baking powder. It submerges and resurfaces on its own as if it were a real miniature working submarine. Fill with baking powder (baking powder not included), shake vigorously under water a few times, and let the fun begin. An excellent stocking stuffer, this is also a good way to show how chemical reactions occur in a classroom setting.
