Paramecium

Paramecium are microscopic single-celled organisms that live in stagnant fresh water
and move with filamentous structures present around the body: cilia. These have two
functions: to allow the paramecium to move and to remove the water around it to
capture organic matter as food.
When moving through the water, the paramecium follows a spiral trajectory, rotating
relative to the major axis. The work is made from stainless steel tubes
counterweighted internally with solid steel, connected together in a way that
transmits the oscillations. By simply touching it with your hand, you get an undulatory
motion; for the safety of the public, the movement is mechanical, but what is it caused
by? Find out for yourself…
