  Paper strips, e.g. confetti, descending to the floor begin to rotate around
the horizontal axis after a short time. This slows down the vertical velocity
compared to free fall and adds a horizontal velocity component. The frequency
of rotation, the angle of fall and the speed of fall seem to depend on the
dimensions and mass of the paper strips. The physics of this flight can be
described, i.e. the movement, the translation of the centroid (energy analysis,
force analysis, formula for fall speed v(b,h,m), formula for angle of fall
{\alpha}(b,h,m)), the rotation around centroid (formula for frequency f(b,h,m),
rotation speed), the flight path with the results from translation and
rotation, the visualization of air turbulence and the loss of energy.
