Dominoes
Dominoes is a classic game played by kids and adults everywhere. One of the more interesting things done with dominoes (and all kids do this) is to line them up and then knock one over and watch the others fall in succession. This idea of one action causing others is often referred to when a courageous action by a brave soul elicits more of the same by others. It appears that this is now happening with regard to investigating election fraud in the 2020 presidential election.
