Diving Submarine

Powered by baking powder, it dives and surfaces just like a real sub.

Description

Remember the submarine toys you used to find in cereal boxes? This little submarine works the same way. Powered by baking powder (not baking soda), it dives and surfaces just like a real submarine. As the baking powder reacts with the water, carbon dioxide is produced. This gas forces water out of the submarine decreasing its density and allowing it to surface. This is much the same way a real sub surfaces by purging its ballast tanks. After the sub reaches the surface, the gas bubble is allowed to escape, water takes its place, and the sub dives again. Approximately 11.4 cm (4.5") long and wonderfully detailed, this is a great science toy for discussing buoyancy, density and the production of CO2.

The diving submarine is a great attention grabber and a great toy to play with. I still remember the sub I had to play with as a child. My Duke students also enjoy playing with them, but I found understanding the concepts that underlying the action of the sub are challenging for them to fully grasp much less for a small group of 3rd grade students whom I challenged to come up with an explanation. After a period of play and observations, I left the students with the challenge of coming up with a full and detailed explanation of how the sub works including the chemistry. I left the teacher with small bottles of each ingredient in baking soda along with all safety information, and several toy submarines. I told the students that I would return in one month and at that time they were to report on the experiments they attempted, the results of each, and their final conclusions. When I returned, I was totally impressed hearing their tests conducted, and their results and conclusions. They determined which chemicals created the gas bubbles, why the water was necessary in the formation of the gas bubbles, and why the sub rose to the surface and then sank back to the bottom. While I am fairly sure their teacher gave the students some guidance, hearing from the students the experiments they attempted in the process to reach their final conclusions, informed me that the students themselves did much of the creative thought in the design of the tests to perform and conclusions they reach from their observations of each experiment. While these 3rd grade students were viewed as being gifted and talented, still I was very, very impressed with their research and conclusions. The one negative I would say would be the ability to provide enough subs and chemicals for students and teachers at different schools, and to find instructors with the time necessary to carry out such a project.

Needs a little finesse

I bought this for teachers in a science workshop to help them think about floating and sinking. Some of the submarines rose and sank quickly. Some never did. The directions are a little vague and need a little finesse and experience to work properly. Some of the teachers were disappointed in their submarines as a result.

this toy is how I first found this company, teaching density to chemistry students was so much more fun...

Best and fast service that I've ever experienced. When I received the box with the 5 submarines it made me feel like a kid again. I'm 67 and retired and I can remember back 58 years when I opened that cereal box and found the submarine inside. Thanks for the memories from long ago. Keep up the great work.

this is a really cool concept. Great teaching tool. I wish it had more of a submarine looking paint finish to it, but i suppose i could do that myself :)
