A nautical marvel! This classic toy, reminiscent of the subs in 1950s cereal boxes, runs on baking powder. It dives and resurfaces autonomously, just like a real mini - working submarine. Fill it with baking powder (not included), give it a good shake under water, and start the adventure. Ideal for kids aged 3 and above.

Using this diving submarine is super easy. First, make sure you have baking powder, as it's not included with the toy. Open the submarine and fill it with baking powder. Then, take it underwater and shake it vigorously a few times. Put it in the water, and watch it submerge and resurface on its own. As for safety, keep it away from small children who might put parts in their mouths. Also, don't over - fill it with baking powder. For maintenance, after each use, dry the submarine thoroughly to prevent rusting. Store it in a dry place when not in use.
