Abstract: During the pandemic period,experiments in home are set up in basic physics
experiment course. Because of the simple preparation and easy measurement,the hand-crumpled
paper ball experiment is chosen by many students. In this paper the fractal in the
experiment of crumpled paper balls is discussed. The definition of fractal dimension is
introduced to describe the internal irregularity of the crumpled paper balls. The fractal
dimen- sion of normal A4 printing paper is measured experimentally and the influence of different
paper hardness and paper layers on the fractal dimension of paper ball is studied.
Key words: fractal, fractal dimension, paper ball
