thicker side, and it was thrown upwards with the thin end to then pull the 
rope, which allowed a spin up and down, thereby printing great spinning 
speed  (torque  speed,  as  this  momentum  is  called  in  physics),  which 
occurred physically in its metal tip. 
Well,  this  type  of  movement  constitutes  a  temporal  system,  in 
which, of course, the child is part of it, given his intervention to initiate 
the movement; but also, in his spinning, the spinning top can be hindered 
by the action of the same child that set it spinning (or of another child, to 
prevent its opponent from winning). In this way, a system is constituted 
that we could call a finite system under threat, since its existence in time is 
not  only  short,  but  minimal,  as  such  a  system,  due  to  the  threats  of 
untimely interruption. In this sense, the spinning top as a finite system is 
threatened by an environment that is volatile, since we do not know what 
circumstance  during  its  spinning  may  force  it  to  break  the  equilibrium 
that sustains it "dancing" with the same force with which it was launched. 
The  spinning  top  is  threatened  by  the  volatility  of  the  environment 
formed  by  the  players  and  the  environment,  the  uncertainty  of  its 
duration as a system, the complexity that constitutes it (a solid piece of 
wood, a metal tip, a long rope, the action of rolling it up and throwing it 
into the spin, the surface where it spins, the children around it, etc.), but 
also  the  ambiguity  of  its  movement  (caused  by  the  back  and  forth 
produced by  the spinning speed, the obstacles of the surface, its initial 
torque, etc.). 
This system of the spinning top, finite by definition, will stop at 
some point, since the friction of the surface will make it slow down until 
it stops. Therefore, it is also made up of a structure whose composition 
has  all  the  complexity  to  be  such  a  finite  system,  but  not  before 
possessing  a  certain  characteristic  as  a  system:  the  uncertainty  of  its 
permanence as a system, since it will disintegrate as a whole when it stops 
definitively, ceasing to be a system as such: its existence is uncertain and 
finite, although its duration is not known (the strategy consisted precisely 
in giving it more torque so that it could remain much longer; my brother, 
a year younger, was always better than me in this game). And this is what 
also  defines  its  complexity  as  a  system,  so  that  interpreting  when  it 
becomes a  system, going from  a mere  static object to a finite dynamic 
object, allows us to determine it as an uncertain but fun object (the fun 
consists in giving it enough force for its longer temporal duration). The 
spinning top is a system as threatened by VUCA environments, or BANI, 
depending on how you look at it.
