Metadata Show full item record. Cartesian Diver Hello. How can a submarine sink or rise? One way is to change the amount of water in the ballast tanks. But how does this cause sinking or rising? We can understand the behavior by considering a simple physics demonstration called a Cartesian diver.
Submarine showing air vents, water intake, and double hull which serves as the ballast tank. Demo Here is our Cartesian diver apparatus. It is a flexible clear 2- liter soda bottle with an inverted glass test tube inside. The test tube is open, and it contains some air. The yellow tape around the tube and cork at the top of the bottle allow the test tube to be clearly seen in a classroom. The bottle is filled with water and securely capped.
There is enough air to make the test tube float. Without the air, it will sink. There are different ways that the diver can be made to sink and rise. One is by telekinesis: using only your mind to move objects. This takes a lot of practice and concentration. The Cartesian diver is a well-known physics demonstration and toy. To learn more about this force, check out The Pressure of Water experiment.

Malcolm Apr 27, Apr 28, Great information, Malcolm! Thanks so much for sharing what you know with us! Jan 29, Jan 21, Sep 27, Dec 20, Dec 21, Thanks for stopping back by Wonderopolis!
William Sep 5, Sep 8, Thank you for making this it was very interesting how they used compressed air to sink and float. I wonder what it would be like to work on one. Jun 22, John from England Apr 8, I do not like submarines and this website is dumb. Wonderopolis Apr 8, Wonderopolis Feb 24, Charlie Jun 12, This article was a very clear explanation for how a submarine works and I liked how they explained how buoyant force works.
I never knew it was so complicated. But I have one question, how does the captain control the submarine with his crew? Wonderopolis Jun 12, Nathan Mar 18, It seems like a cool experience going on a sub. Wonderopolis Mar 18, Who goes down there? Besides the one who drives it. Wonderopolis Mar 15, I think I would be scared to because I'm very scared of a submarine.
Don't you? Wonderopolis Mar 12, Michael Mar 11, I would be soooooooooooooooo scared if I was on a submarine. Being under the water gives me the chills. I always thought it would fill up with water.
Now I know it won't. Wonderopolis Mar 11, Reico from Mrs. Bahler's Class Mar 11, Bahelr's Clas Mar 11, Asia from Mrs. I wonder why it is so bright when the people look out the window of the sub while they are underwater.
