This updated Diving Sub is great for building connections between science and toys or introducing a simple chemical reaction. You'll receive an awesome submarine measuring 112 mm (4.5") as well as directions on exactly how to get the best action out of your sub. Ages 6 and up.
How does it work?Just fill the submarine with the baking powder and you're ready to make the subs dive and surface many times.
What does it teach?Great for building connections between science and toys or introducing a simple chemical reaction.
- Why do I have trouble getting them to dive sometimes?
They should dive and surface multiple times if you follow the directions. One thing is to make sure that you are using enough baking powder.

These Mini Diving Submarines are great. However, baking soda does not react with water; you need to use baking powder. Just make sure you use fresh baking powder.
