Mysterious Physical Phenomenon: Balancing a Badminton Racket in Water

AI Thread Summary
A badminton racket can balance upright on its head at the bottom of a swimming pool due to the principles of density and buoyancy. Although the handle is heavier, it is also thicker and occupies more space, resulting in lower overall density compared to the head. This difference in density causes the handle to experience a greater buoyant force, making it float, while the head remains dense enough to sink. The phenomenon highlights that weight alone does not determine whether an object floats or sinks; density plays a crucial role. Understanding these principles clarifies the unexpected behavior of the racket in water.

Hello. Today I came across a physical phenomenon ..
I played badminton in France, at the swimming pool. So I lost my paddle in the pool. (A badminton racket looks like a tennis racket)

In the water, no matter how I throw the racket down, balancing it on the head in the bottom of the pool, not the handle, but on the head by strings. It stands straight up.

How can this be? The handle is heavier than the head of the racket, but why it does not float, and how it manages to balance perfectly on the bottom of the pool? It would never made it on land ...

It is not truly weight that matters, but density. The handle may be heavier than the rest of the racket, but it is also much thicker. It takes up much more space. So, overall, it is less dense. Therefore, the buoyant force on the handle is greater, making it want to float, while the rest of the racket is dense enough to want to sink.
 
Thanks, getting a grip to it now!
 
comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
