How do you make a submarine with baking powder?
To make your submarine work you’ll pack the hole with baking powder and set it on the bottom of a tub or bowl of water. The water will react with the baking powder to create carbon dioxide bubbles. The bubbles will get trapped under the submarine and make it come to the surface.
How do you make a submarine bottle sink then float?
Put the cap on and tighten it. Place the bottle bottom-side down into a bathtub filled with water. Water will fill the bottle through the holes in the bottom, causing it to sink. When the baking powder reacts with the water inside the bottle, it will release carbon dioxide gas.
How does the baking powder submarine work?
Baking powder is placed into a compartment in the bottom of the toy which is sealed except for a small hole (or holes). The toy sinks when placed into water, but after a few seconds, enough water leaks in to react with the baking powder and produce carbon dioxide bubbles.

How do you make a submarine bottle?
When placed in water, the bottle fills with water, pulling it down below the surface, then, by blowing air through an attached straw, the water is forced out and the submarine rises again. Not only is this a fun build, with lots of room for creativity, but kids also love to experiment with their “toy” afterwards.
