Mini Diving Submarines Kit

Mini Diving Submarines is from the Kidz Labs Fun Science Products series.

Mini Diving Submarines powered by baking soda. Watch it dive and emerge in a glass. It’s amazing.

The submarine sinks naturally because it is heavier than the water. However, when the water comes into contact with the baking powder, carbon dioxide is released and the release of the gas causes the submarine to surface. When all of the carbon dioxide from one reaction has been released from the submarine it causes the sub to ‘dive’ once again. This process will be repeated until the amount of baking powder left in the chamber has reduced to such a level that the volume of carbon dioxide produced is not enough to raise the submarine again, until the chamber has been re-filled.

Suitable for ages 5 and up.
