Back in the days when technology was a good guy, and cereal boxes came with real toys, kids got diving submarines that they charged with baking powder and played with in the bath tub. Now kids can have the same fun again. We have found a (gray!) submarine, about 4-1/2" long, that can dive and surface up to a dozen times with a single charge of the baking powder that you get to supply. Comes with instructions and made in the USA.
