Artificial water plants that move like an organism. Water is pumped through elastic stems and collects in the calyxes until they bend down, empty and spring back. The movements add up to form combinations, oscillations overlap and influence each other, groups are formed that separate again, then join up with others, this in constant alternation. It can happen that a group interlocks and becomes unable to move. The phenomenon of self-organization can also be observed here: Little by little, those "entangled" find a common rhythm, a synchronous vibration that builds up until the knot falls apart
