Small but terrible

 

This is how bar objects spin

On the first video,objects spin enough quickly to escape from fall because all the required conditions are provided;an axis,the finger,a space and the energy given by the launch shake.

Anyone without a disability can perform the skill of spinning objects by training.It means involving the sense of touch,learning where exactly 

to place the object  on their finger and especially the tough launch shake.

The launch shake is quite similar to the fishers'' but too much shorter.Even shorter than Bruce Lee's  punch but enough to move a pen.It stops where it starts.Watch this nostalgic video :the 1 inch punch

As you see,Bruce Lee's hand stops where it starts.The same conditon is required to spin a pen:The shorter is the shake the better  is the show.

Notice on the slow motion video that there is a big interval between the length of the launch shake and the distance spent by the pen  top.The movement of the hands stop but the pen and the  model of The Dragon keep going thanks to the  initial energy.

This phenomenon is also noticed in other circumstances such  with satellites that travelinig in their orbits with no actual energy.Or with  passengers shaked in a bus when the chauffeur hits  suddenly the brake.Or also,as previously given,when fishers shake their cans roughly and shortly,but the  plugs keep sliding on the lake surface.

How to call this phenomenon in physics?On the previous video,objects spin enough quick

to slip from dropping because all the required conditions are provided;an axe,the finger,a space an

d the energy given by the launch shake.

cans and the  bouchons keep going on the lake surface.

Conclusion:

How to call this remarkable phenomenon in physics?
