: Submarines have ballast tanks. The tanks can hold air, or they can be "vented" and water can flow into them and fill them completely. When the tanks are full of air, the submarine is buoyant and floats. When the main vents are o...

The two shoulder-buttons control the submerge and emerge of the remote control sub. Essentially, there are 3 propellers on the sub. Two control the horizontal direction of the sub, and one controls the vertical depth of the submarine. ... Let's face it, radio controlled submarines are just a cool concept.

The key here is that the Deep Flight Super Falcon doesn't have ballast tanks—tanks which can be filled with water or pressurized air to increase or decrease the submarine's weight—making it to submerge or emerge.

One of them has to do with submarines. The idea would be to explain to kids how submarines submerge and emerge. The submarines are actually water bottles. It's neat. When I saw that I thought that we could attach some sensors to the water bottle submarine and take measures of diving depth and so on.

To submerge, the crew opens vents at the top of the ballast tanks. This lets the air out. The bottom of the ballast tank is open to the sea, so as soon as the air is released water comes in to take its place, the displacement increases, and the boat slips below the surface. ... Submarines are designed so that,
