you can not make air stay under water!
what air under water?????
Dolphins breathe air; they would drown if they never surfaced.
the animal that can swimm longest without coming up for air is a lion they can stay under water for days.
No because they have a blow hole like a whale so they have to come up for air.
The water in the fishbowl is evapourated which forms air bubbles under the leaves in the fish tank because the evapourated water escapes the bowl of water by travelling as a bubble. The leaves in the fish tank traps the bubble under it causing it to stay there.
By not having enough lift and air speed under the wings.
I don't know the exact time but it's only very brief. Just make sure the lungs are full of air and it'll go fine :)
The spiders that stay under water for a very long time are called diving bell spiders. They actually make a kind of inverted silken bowl under the surface of the water. They have spines on their body that let them get a bubble of air to stick to them, so they flip their abdomens out of the water and it comes back carrying a bubble or two stuck to it. They then swim to their "diving bell," go inside, and dislodge the air bubble. So they can stay underwater, hunt, etc., for a very long time. Technically, only their abdomens need to go outside the water, so you could argue that they could spend an entire spider lifetime under the surface of a pond.
Yes. Sharks LIVE underwater, and will die quite soon if taken into air.
Under water they are as buoyant as each other but on land the balloon will float away and the Styrofoam will stay.
Goldfish make bubbles because they release excess air from their swim bladders, which helps them regulate their buoyancy and stay balanced in the water.
Yes, they breathe oxygen, but they have this air bubble like thing in their abdomen that allows them to stay under water for quite some time.
