  Recently, simple scaling laws concerning the mechanical response and
mechanical transition of Kirigami have been revealed through agreement between
theory and experiment for kirigami made of paper [M. Isobe and K. Okumura, Sci.
Rep. 2016]. Here, we provide experimental data obtained from kirigami made of
soft elastic sheets to demonstrate good agreement with previous theories,
although a number of assumptions in the theory are violated and the elastic
modulus is three orders of magnitude smaller in the present case. This
remarkable universality in the mechanics of Kirigami, which could be useful for
applications, is reported with physical insights based on previous theories.
