The balloon floats because of the buoyant force exerted on it. An object that floats in the water is known as being "positively" buoyant. The result is a light and strong surfboard that is buoyant and maneuverable. Compared to buoyant flow, the neutrally buoyant flow shows completely different behaviour. Moored buoys are connected with the seabed using either chains, nylon, or buoyant polypropylene. This fat also makes large toothfish neutrally buoyant. Since the gas is more buoyant than the liquid, the convective pressure is greater. Exports stagnated and Pakistan lost its market share in a buoyant world trade environment. Training in a viscous, buoyant fluid gave a better simulation. Once aerial, with its buoyant but erratic flight, this bird is most conspicuous. In continental Europe, thinner yet slightly buoyant line is typical. This makes them negatively buoyant and durable in the chlorinated water of swimming pools. Most marine teleosts have pelagic eggs, which are light, transparent and buoyant with thin envelopes. This allows more efficient locomotion among these negatively buoyant cartilaginous fish. Coconut fruit in the wild are light, buoyant, and highly water resistant.
