Diving Sub

  • A classic cereal toy promotional item from the 1950's.
  • Watch in amazement as it dives and resurfaces again and again, powered by ordinary baking powder.
  • The Submarine is denser than the water and sinks to the bottom.
  • As the water reacts with the baking powder, harmless carbon dioxide gas is formed and creates bubbles, making the submarine rise to the surface.
