Exciting plays and talks

I took my grandson from school, he is on the first class.  We played with these toy cars on a cliff and discussed about infinity.  As a retired  teacher of statistics  I cannot give up telling to my only listener  about statistical distributions.  My grandson knows the shapes of even, normal, poisson and cauchy distributions.He understands also the consepts of mean  and standard deviation. But   especially cauchy distribution fascinates my grandson.  The distribution is exciting because it can be get by dividing two observations that obey standard Normal distribution. It means that the distribution may continue to infinity.  We were pondering could two observations be on different levels on the way to infinity.
