If beer replaced water, swimming would be a very different experience. For one thing, the buoyancy of beer might be different from that of water, so it could be more or less difficult to swim depending on the specific gravity of the beer. Additionally, beer is not as clear as water, so visibility while swimming might be reduced.

As for the effects of being in the beer for an extended period of time, it is possible that you could become intoxicated if you stayed in the water long enough. Alcohol can be absorbed through the skin, and the longer you are in contact with the beer, the more alcohol you could potentially absorb. However, it is difficult to say exactly how much beer you would have to be exposed to in order to become intoxicated, as this would depend on a variety of factors such as the alcohol content of the beer, the size of the person, and the duration of exposure.

It’s worth noting that while the idea of swimming in beer might sound fun, it is not a practical or safe substitute for water. Beer is not a suitable medium for swimming or other activities that require hydration, and it is important to stay properly hydrated with water or other suitable beverages.
