The domino effect and the principle of
momentum conservation took place after
the earthquake in the library, thus the
book shelves arranged in neat rows hit each
other under the principle of momentum conservation,
resulting to the shelves falling down due to the chain
reaction.
Where else can you use these types of mechanisms?

“It’s about to begin!”
It’s now 7:58 in the evening. In two minutes, the
program Dominos of the Century is about to come
on TV. Lately, Catherine’s whole family has been
hooked on the dominos show!
Dominos originated from China in the 12th century
and were mostly made from animal bones, which
is why they were called bone tiles. The use of
dominos originated from dice, but had more
complicated rules. When dominos were introduced into Europe, wooden tiles
were mass produced in order to increase their accessibility. There was also a
new method of “connect and knock down” play introduced where one domino is
pushed which knocks down the next one and so on, to produce a chain reaction
called the “domino eect”.
Catherine felt that the appeal of dominos came from the combination of creative
design, precise calculations, and teamwork to achieve a magical sight for
audience members.
Catherine really wanted to participate in a game of dominos to show o her skills,
but the diculty level of the TV show was too high. So, her brother began to teach
her basic domino moves. Three rectangular frames were arranged from top to
bottom, the rst frame hit the middle piece which then hit the last piece, creating
a thrilling cascade of movement.
Kids, let’s try it together!
