  The conditions are investigated under which a row of increasing dominoes is
able to keep tumbling over. The analysis is restricted to the simplest case of
frictionless dominoes that only can topple not slide. The model is scale
invariant, i.e. dominoes and distance grow in size at a fixed rate, while
keeping the aspect ratios of the dominoes constant. The maximal growth rate for
which a domino effect exist is determined as a function of the mutual
separation.
