When the dominos are standing, their center
of gravity is higher. The bottom of the domino
and the ground’s surface form a right angle;
therefore, the domino produced no torque and
remains standing. However, once the domino is hit on
the side by an external force, the produced torque uses the
ground as a fulcrum. This force shifts the domino’s center of
gravity, causing the domino to fall. When dominos fall, they produce torque,
which can cause nearby domino pieces to fall as well in a sequence. This
chain reaction is known as the “domino effect”. If dominos are appropriately
placed on a staircase, the transmission of torque from the first domino
falling can make the domino effect look like it is climbing up the staircase.

After dinner, Grandpa Rudolph told Tony that he wanted to show him a new
domino game that he had never played before. Curious, Tony asked what it
was. Grandpa Rudolph explained that Tony would recognize it after giving
Grandpa all his new erasers and steel rulers.
Thus, Tony went to his study and got everything Grandpa Rudolph had
asked for. First, Grandpa Rudolph took the two erasers and placed them
underneath the middle of the ruler, using them as a fulcrum. Then, he
placed the rest of the erasers at an equal distance apart on top the steel
ruler. It was a domino seesaw!
Tony lightly push the bottom domino. The
tumbling domino successfully initiated the
domino effect. When the top eraser was
knocked down, the top side of the seesaw
moved down.
Kids, do you understand the principle
behind rising dominos? Follow the steps
and make a tower!
