Can you breathe underwater with air bubbles?
if you have a bubble of oxygen you can breath it, but unless there is something capturing the bubble, like an inverted bucket. That bubble will be moving toward the surface much faster than you can and a lot faster than you can decompress. The solubility of oxygen is greatest around 4 degrees centigrade.
Are there any animals that breathe air and water?
Amphibians are vertebrates (animals with backbones) which are able, when adult, to live both in water and on land. Unlike fish, they can breathe atmospheric oxygen through lungs, and they differ from reptiles in that they have soft, moist, usually scale-less skin, and have to breed in water.

What is your opinion about the polar bear needs fat to stay warm?
Almost every aspect of the polar bears design is engineered for warmth. Their bodies are designed to be lined with a cozy layer of fat, which can be up to 3.4 inches thick. This fat not only helps polar bears keep warm, but acts as an energy store for slow hunting periods.
How long can I live in a sealed room?
Simply put, humans don’t take in as much oxygen as we think we do. Based on oxygen alone, estimates are that the average person could survive in a completely sealed room for 12 full days!
Can you survive in an air bubble?
In an air pocket, the first problem is carbon dioxide build-up. Every time you exhale within the bubble, you release toxic carbon dioxide into a closed space. To survive 100 feet underwater for three days, then, you’d need about six cubic meters of air—or a bubble about the size of a small dumpster.
How do you hold your breath for 5 minutes underwater?
