This diving submarine is powered by baking powder. Simply fill the submarine with baking powder, place it in water, and watch as it submerges and re-surfaces over and over again. An excellent stocking stuffer, this is also a good way to show how chemical reactions occur in a classroom setting.
Features:
- Diving submarine dives and re-surfaces using baking powder (baking powder is not included)
- Submarine is approximately 4.5" long
- Great as a stocking stuffer or small chemistry project
