Domino Line

A Domino line is a line of dominos in a line. This is the main toppling part of domino rallies, otherwise nothing would topple at all. This is very simple to set up.

Set up

 * 1) The first step is to get a pile of dominos. Make sure they have flat ends otherwise they will fall easily.
 * 2) Put the ends (portrait) on the floor. Do this with more dominos to make a line.
 * 3) Push the first domino and watch it topple!
