A submarine is like a secret underwater boat that can swim under the ocean and hide from view.
Imagine you're playing with your toy boats in the bathtub, now picture one of those boats growing really big, strong enough to go all the way down to the bottom of the sea. That’s what a submarine does! It can dive deep into the water, just like a fish, and then pop back up to the surface when it wants.
How Submarines Move
Submarines use special tanks inside them that fill with water or air. When they want to go underwater, they let in water, this makes them heavier and helps them sink. When they want to rise back up, they push out the water and let in air, like blowing bubbles in the bathtub!
Fun Facts
