have the same size and weight
to ensure each of them topples
up to the last one in the line.
this is called the domino effect
or a chain reaction
where one incident
sets off a series of other incidents
until everything becomes a disaster.
Think about what a tiny flame
from a match stick can do
to engulf the whole house on fire,
as what usually happened in fire emergencies.
there is a domino show
that involves tiles of varying sizes
that still do the same toppling chain,
the first of which is very small or tiny
and the last one is very big and heavy.
Never thought this could be possible.
