Can you post a picture of the whole thing please
The reason is that a closed system has nothing going in or out and water retains energy very well also water it polar so it is attracted to itself. It doesnt like contact with other things.

from the principle of flotation which states that a
When a body displaces a weight of water equal to its own weight, it floats. : A floating object displaces a weight of fluid equal to its own weight. ... Archimedes' principle equates the buoyant force to the weight of the fluid displaced.
the upthrust (this is the upward vertical force exerted on an object in fluid)in the water equals the weight of the body in water it floats.
